Multi Power Tools: specifications, types
Show all
Product type
— Rotary engraver. A tool designed mainly for engraving and using a rotating working head for this. However, engravers can also be used for other types of work — drilling, cutting, grinding, etc. In fact, they are hybrids of drills and grinders with low power and compact dimensions (both the tool itself and the working nozzles).
— Impact engraver. A type of engraving tool in which percussive action is used for processing. Such models have a narrower specialization than the rotary engravers described above; they are practically not used for purposes other than engraving and embossing.
— Renovator. A specific type of hand tool, which is closest in design to grinders. The key difference is the principle of operation: the nozzle of the renovator does not rotate during operation, but vibrates finely at a high frequency. The variety of nozzles themselves is very large, which allows you to perform a wide range of work: grinding, cleaning, cutting, sawing, etc. Most of these models, however, lose out to specialized units like electric saws or electric jigsaws, however, with relatively simple work of a small volume, the renovator may well replace several tools at once. In addition, such tools can be useful in difficult cramped conditions, and the accuracy and accuracy of processing is often higher than when using the same saws.
— Multitool. In accordance...with the name, this variety is the most versatile and diverse in terms of equipment. The design of the multi-tool includes the main unit and several removable heads, by changing which you can turn the tool into a drill, renovator, jigsaw, etc. On the one hand, it is convenient — it is easier to carry one universal unit with you than several specialized ones, despite the fact that the power and performance of such devices can be quite high. Also note that if necessary, additional heads can be purchased separately. On the other hand, the mentioned versatility is rarely required in fact, and the tools themselves are expensive. As a result, it is often easier to purchase individual specialized models than to shell out a "round sum" for a multitool or look for additional interchangeable heads that are not sold everywhere. Therefore, there are relatively few models of this type on the market.
— Electrochisel. A tool designed as an electrical analogue of a conventional chisel used in joinery, carpentry, and woodcarving. In electric chisels, the blade vibrates at a high frequency; due to this, such a tool can be used not only for removing a layer of wood, but also for chiselling, similar to a chisel (and, unlike a conventional chisel, without using a hammer). As working nozzles, scrapers (see "Nozzles") of various shapes and widths are used; in some models, the number of nozzles in the kit can reach one and a half dozen.

Interchangeable heads
Types of interchangeable heads supplied with the multitool(see "Device"). The most common options are:
— Renovator. A renovator is a tool that uses the vibration of a working nozzle to carry out various types of work. For more details, see the relevant paragraph above, in paragraph "Device".
— Drill / screwdriver. Usually, in this case, a universal head is meant, suitable for working both as a drill and as a screwdriver. However, the features of such heads and their suitability for different types of relevant work may be different, so the specifics of the application in each case should be clarified separately.
— Electric jigsaw. Head for sawing plywood, wood, metal and other materials with a blade moving back and forth. By themselves, jigsaws are usually quite versatile, and their suitability for a particular material is primarily associated with the presence of an appropriate file.
— Delta grinding. A specific type of grinder — it uses a triangular nozzle for work, similar in shape to the Greek letter "delta" (hence the name). Like renovators (see above), they work on the principle of vibration of the working nozzle. Such machines are used mainly in specific places where it is impossible to use another tool — for example, on recessed surfaces with corners.

Power consumption
The electrical power consumed by the tool during normal operation. Usually, the characteristics indicate the power at the maximum speed / frequency of movements of the working nozzle.
Usually, the higher this indicator, the more intense the tool can act on the material being processed, the better it is suitable for difficult conditions (large volumes of work, hard materials). At the same time, note that high power significantly affects energy consumption; in mains-powered models (see below), this puts strain on the wiring, and in battery-powered models, it requires the use of bulky and heavy batteries and significantly reduces battery life. Yes, and this parameter significantly affects the dimensions, weight and price of the tool itself. Therefore, it is worth choosing a model according to power consumption, taking into account the specifics of the work for which it is planned to be used: for example, it hardly makes sense to purchase a high-performance professional tool for minor repairs around the house or in the country.
Specific recommendations on the optimal power values, depending on the type of tool and the purpose of its use, can be found in special sources.

Rotation speed
The speed of rotation of the working nozzle provided by the tool. Some models have a fixed rotation speed, others allow you to adjust it within a certain range (see "Number of speeds").
For different types of tools and types of work, different values of this parameter will be optimal; therefore, it is worth choosing taking into account the tasks that are planned to be solved using the tool (it is best to consult with special sources). We note only a couple of general patterns. So, for engraving on relatively soft and pliable materials (wood, glass, soft metals), high speed is not required, but for hard and difficult to process (steel, precious stones), a high-speed tool is better suited. But when drilling, note that for the same power consumption (see above), more revolutions, usually, means lower torque values. That is, here “high-speed” tools are better suited just for soft materials, and low-speed tools are better suited for hard and heavy materials.

Number of oscillations
The vibration frequency of the working head, provided by the tool in the renovator or delta grinding mode (for more details on the modes, see "Replaceable heads"). For different types of work and different materials, the optimal frequency values \u200b\u200bwill also be different; therefore, when choosing, it is worth consulting the reference literature or a specialist and making sure that the selected model will provide the required number of oscillations.
In some models, this parameter can be adjusted - this makes the tool more versatile.
In some models, this parameter can be adjusted - this makes the tool more versatile.
Stroke
The amplitude of movements performed by the working nozzle, in other words, the distance between the extreme points of the stroke. This parameter is relevant primarily for electric chisels ; at the same time, in most models, the stroke does not differ much from the standard indicator of 2 mm, which is quite sufficient for use for its main purpose, and this parameter is more of a reference than practically significant.
Max. blows per minute
The maximum frequency of blows given out when working with an impact engraver (see "Device"). Most of these tools allow you to adjust the operating frequency, so it is customary to indicate its maximum value in the characteristics.
The greater the number of strokes over a period of time, the more intensive the processing and the better the tool will cope with hard, difficult-to-process materials. Specific recommendations on the optimal value of this parameter can be found in special sources.

Oscillation angle left/right
Oscillation angle of the renovator nozzle; indicated both for the actual renovators (see "Device"), and for multi-tools with the appropriate nozzles.
Initially, this parameter is usually measured from the middle position of the nozzle; accordingly, the total amplitude will be 2 times greater — for example, for a model at 1.5 ° it will be 3 °. Note that the standard values of the oscillation angle in renovators are 1.4 – 1.6° and rarely go beyond these limits. In some models, figures of 2.5 ° and even more are given; however, most often this means that the manufacturer did not indicate the deviation from the middle, but the overall amplitude.
In general, this parameter is not critically significant: different models of the tool do not have any particular differences in the angle of oscillation, and other characteristics affect the capabilities of the renovator.

Number of speeds
The number of speed adjustments provided in the design of the tool.
The high speed ensures good productivity and can handle difficult materials. At the same time, there is not always a real need for it, and a high frequency of revolutions / vibrations can lead to excessive consumption of electricity, and in some cases to a deterioration in the quality of processing. Therefore, in some models there may be several speed adjustments — this allows you to choose the best option depending on the current need.
The more such adjustments, the wider the choice of the operator. At the same time, the technical features of modern instruments are such that there is usually no need to provide more than three fixed speeds in them. If more precise adjustment is required, manufacturers use smooth speed control (see "Functions").

Collet diameter
The diameter of the collet provided in the design of the rotary engraver (see "Device").
A collet is a specific type of fastening: a split sleeve, the “petals” of which can be compressed and unclenched by twisting / unscrewing the clamp. For a number of technical reasons, this mount is considered optimal for engravers. In order to properly install the working nozzle in such a tool, it is necessary that it fits the diameter of the collet (to be more precise, the mounting size of the nozzle should not exceed this diameter).
Note that there are several standard collet sizes. The most popular is 3.2 mm, but there are other options. And some engravers can be equipped with several mounts of different sizes.

Functions
- Reverse. Possibility to change the direction of rotation of the working nozzle of the tool. The use of reverse depends on the type of tool and the type of work for which it is used. For example, when drilling, this function can be useful for releasing a jammed drill. And in screwdrivers (see "Interchangeable heads") a change in the direction of rotation is almost mandatory - otherwise it would be impossible to switch the tool from twisting to loosening and vice versa.
- Speed controller. The ability to smoothly change the speed of movement of the working nozzle (frequency of rotation or vibration). The adjustment itself is used to adjust the tool for different types of materials and work - for different cases, the speed is different. But smooth tuning is good because it allows you to set the required speed as accurately as possible - there are no strictly fixed adjustments in such models, and the operator can choose any option from minimum to maximum. True, a certain skill is required for the effective use of such a tool, but this problem can hardly be called serious even for beginners.
- Maintain momentum. A function that allows you to maintain a constant speed of rotation of the nozzle, regardless of the load on it. Without special adjustment, at a constant engine power, the rotational speed inevitably drops with increasing load and increases with...a decrease. And the revs control system monitors the resistance on the nozzle and, if necessary, changes the power in such a way that the rotation speed remains constant. This has a positive effect both on the quality of work and on the service life of the nozzles and the entire tool.
- Soft start. The moment of starting is one of the most difficult in the operation of any electric motor. When the power is connected directly, in the first moments after the start, a high power flows through the windings, which leads to voltage surges in the network; in addition, the beginning of the movement occurs very abruptly, and this is fraught with jerks of the instrument, with the risk of releasing it from the hands with corresponding unpleasant consequences. The soft start function reduces the described troubles, if not to zero, then to a minimum: special circuits limit the starting power and ensure a soft and safe start of movement.
- Brushless motor. The presence of a brushless (brushless) motor in an electric tool. Such motors are noticeably superior to traditional collector motors in terms of efficiency, which makes it possible to significantly reduce energy consumption without sacrificing power; this is especially important for cordless tools (see "Power Source"), where this feature is predominantly found. In addition, brushless motors are less noisy and generate virtually no sparks during operation, making them ideal for working in high fire hazard environments. Their main disadvantages are traditional - the complexity of the design and high price.
— Backlight. The tool has its own lamp to illuminate the place of work. This feature is especially useful when working in low light conditions or in hard-to-reach areas that are otherwise difficult to illuminate. Note that in this case, it is the embedded system that is meant; some models may be equipped with portable lights as separate units, but such lights do not count as lights.
- Display. Own display in the design of the multifunctional tool is designed to visualize customizable parameters, display the battery charge level and display all sorts of related information. The specific implementation of the screen depends on the level of functionality of a specific instrument model.
- Connecting a vacuum cleaner. Possibility of connecting the vacuum cleaner directly to the tool. For this, a special pipe is usually used, one end of which is led to the place of processing, and the actual hose from the vacuum cleaner is connected to the other. Thanks to this, the work becomes much “cleaner”; True, the vacuum cleaner is far from always 100% able to remove sawdust and other waste, but in any case, it at least simplifies subsequent cleaning. The hose nozzle is usually made removable - this allows you to reduce the overall dimensions of the tool in cases where the vacuum cleaner is not needed or is not within reach. Note that before buying a model with this function, you should pay attention to its compatibility with the specific vacuum cleaner that you plan to use.
— Keyless replacement of nozzles. The presence of a clamping tool in the design that allows you to replace working nozzles without using a key. There are many varieties of such clamps, differing in the procedure for use, but they all have one thing in common: the work with the mount is carried out by hand, without the use of keys or other additional devices.

Total number of nozzles
The total number of working attachments supplied with the tool.
The abundance of attachments allows the machine to be used with various materials and for various types of work. At the same time, this parameter significantly affects the cost. Therefore, when choosing, you need to proceed from how important a variety of possibilities is for you - so as not to overpay for extra nozzles that turned out to be useless in fact.
Note that this item is indicated only for engravers (see "Device") - for models of other types, specific types of nozzles are given in the corresponding item (see below).

Nozzles
Types of nozzles supplied with the tool.
— Delta platform. Grinding nozzle with a characteristic triangular shape. It is an obligatory element of equipment for tools with the function of a delta grinder (see "Interchangeable heads"), however, it is also often found in renovators (see "Device").
— Segmented disk. A nozzle in the form of an "incomplete" disk — a circle that has no segment. Such a nozzle is only suitable for processing using vibration, and therefore it is found exclusively in tools with a renovator function (see "Device", "Interchangeable heads"). At the same time, the shape of the nozzle allows you to work with both the front and side parts, which gives you freedom of manoeuvre.
— Chaber. A scraper usually means a plate of a rectangular (or close to it) shape. Such a nozzle is one of the most popular in renovators (see "Device", "Replaceable heads") due to its versatility: it is suitable for scraping, cleaning surfaces, cutting, etc. In addition, the scraper is traditionally used as a regular nozzle for electric chisels .
— Saw blade. Specialized nozzle for sawing various materials. Its design and method of operation may vary depending on the specifics of the tool: for example, in electric jigsaws (see "Replaceable heads") the saw blade is designed to move back and forth and looks...like a characteristic strip, in renovators it looks like a narrow plate, etc. .
— For stitching seams. Nozzle for processing joints between tiles, bricks, etc. to give them a neat appearance. It is worth considering that the shape of the jointing can be different (convex or recessed, straight or rounded, etc.), respectively, and nozzles for such work can have a different shape; specific features should be specified separately for each instrument model.
- Sheets for grinding. Sheets for grinding and polishing stone, wood or metal products on a special plate with fastening to the executive body of a multifunctional tool. They often have a triangular shape; sandpaper or diamond coating is used as the material for their working surface.
Note that these are far from all types of nozzles that modern universal tools can be equipped with, but only the most popular ones. In addition to them, other devices may be included in the kit — for example, a variety of sanding sheets. And the “set of nozzles” option is indicated for tools (mainly engravers, see “Device”), the equipment of which includes several dozen devices; in some models, this number may exceed one and a half hundred.

Power source
The type of power used by the tool to operate.
— Network. Powered by a conventional household network of 230 V. This option allows you to create units of almost any power — within the range that can be useful for a hand tool. At the same time, such models, other things being equal, weigh less and cost less than battery ones, and when working with them, you do not need to monitor the state of the battery, risking being left with a “dead” tool at the most inopportune moment. Their main disadvantages are dependence on sockets and the presence of a power cord, which limits mobility, can create inconvenience and requires extra care (so that the cable does not get under the working nozzle).
— Battery. Powered by its own built-in battery. Such a tool is extremely mobile and easy to use — it does not require a network connection, which allows you to work even if there are no outlets nearby. And the absence of a cable has a positive effect on convenience and safety. On the other hand, the power of battery models is generally lower than that of mains ones, and the battery itself significantly increases not only the price, but also the weight and dimensions of the unit — modern tools consume a lot of energy, which means that they need appropriate batteries. In addition, the battery life is limited, and when the charge is exhausted, the battery will have to be charged, which takes time and the ava...ilability of power. This disadvantage in some models is compensated by the presence of a spare battery in the delivery set (see "Replacement battery"), but only in part — the second battery increases battery life, but does not eliminate the need to charge dead batteries. In view of all this, it is worth paying attention to models with such a power supply only when the ability to work without sockets is critical for you.
— Batteries. Models powered by replaceable AA batteries and some of its derivatives. A similar way of power supply is implemented in low-power tools in the manner of compact rotary engravers.

In view of all this, it is worth paying attention to models with such a power supply only when the ability to work without sockets is critical for you.
— Batteries. Models powered by replaceable AA batteries and some of its derivatives. A similar way of power supply is implemented in low-power tools in the manner of compact rotary engravers.
Battery in set
The number of batteries supplied with the respective tool (see "Power Source"). Also, this item may indicate the presence of a built-in battery.
The most popular configuration option with a battery in our time is 2 batteries. This provides additional benefits, which are especially convenient for long continuous use of the tool. So, when the charge of one battery is exhausted, you can quickly change it to another; while one battery is in use, the other can be charged. This minimizes or eliminates interruptions in charging. Single battery kits are not particularly common: they are mainly entry-level tools designed for small amounts of work, when charging breaks are quite acceptable.
In addition, quite a few modern cordless tools come without batteries. This configuration assumes that the customer himself will purchase batteries at his discretion (many models are compatible with several brands of batteries at once). In addition, this option may come in handy in case the battery is already on the farm. This happens quite often, since many well-known manufacturers use universal batteries suitable for different types of branded power tools. So a battery, for example, from a previously purchased electric jigsaw or grinder may well be compatible with an engraver, a renovator of the same company.
As for non-removable batteries, this is a rather rare...and specific option. Such tools turn out to be as compact as possible, but the batteries themselves cannot be quickly changed - so you will inevitably have to take breaks for charging during work. Therefore, this method of supply is typical for low-power instruments. In them, small size is more important than a long period of continuous operation, in addition, a low capacity allows you to achieve good autonomy even with small sizes (and, accordingly, capacity) of batteries.

Battery platform
The name of the battery platform supported by the device. A single battery platform is used to combine various power tools of the same brand into one line (renovator, engraver, screwdriver, grinder, circular saw, etc.). Devices on the same platform use interchangeable batteries and chargers. Thanks to this, for example, there is no need to select a battery for each individual model of a power tool, because one purchased as a spare battery can be used in various power tools, depending on the situation or as needed. Batteries of the same platform basically differ from each other except perhaps in capacity.
Battery voltage
Nominal voltage of the battery supplied with the appropriately powered tool (see above).
This parameter is usually selected by the manufacturer in such a way as to optimally match the specifications of a particular model. Therefore, in fact, it is more of a reference than really meaningful. However, in some cases, voltage information can be useful — for example, if you are looking for a spare battery or want to replace a failed battery.

However, in some cases, voltage information can be useful — for example, if you are looking for a spare battery or want to replace a failed battery.
Battery type
The type of battery supplied with the rechargeable model (see "Power Source").
— Ni-Cd (nickel-cadmium). The most "old" option found in modern power tools. It is distinguished by high reliability, resistance to temperature extremes and good charging speed even with high capacity (which is important, given the "voracity" of the power tool). The main disadvantage of this type of batteries can be called a pronounced "memory effect" — a decrease in battery capacity if it is set for charging without being completely discharged. In addition, Ni-Cd cells are considered environmentally unsafe. Nevertheless, they are still widely used in tools — not least due to their low cost with decent performance.
— Ni-Mh (nickel-metal hydride). Such batteries were created as a development of the nickel-cadmium batteries described above. Retaining all the main advantages of their predecessors, they are at the same time devoid of most of the shortcomings — in particular, they are practically not subject to the memory effect. Of the own shortcomings of this option, it is worth mentioning a slightly lower durability and higher cost than the original Ni-Cd.
— Li-Ion (lithium-ion). A type of battery originally developed for use in portable devices; however, with the development of Li-Ion technology, it has also been used in power tools. The main advantage of such batteries in this case can be called a high capacity with small dimensions and weight. It is also worth noting...that they are not subject to the memory effect and are able to charge quite quickly. On the other hand, this option is not without its drawbacks — this is, first of all, sensitivity to too low or elevated temperatures, as well as a high price.

Battery capacity
The capacity of the battery that the tool with the corresponding type of power is equipped with (see above).
Capacity is essentially the amount of energy a battery can store. The more powerful the device, the more energy it needs to work and the higher the battery capacity should be so that it does not have to be charged too often. At the same time, capacious batteries have a large weight and dimensions, which significantly affects the convenience of work. Therefore, the power of the battery tool is relatively low — otherwise, too bulky batteries would have to be used.
To some extent, this parameter also determines the time that the tool is able to work without recharging. However, taking into account the fact that different models can noticeably differ in power consumption, it makes sense to compare with each other by battery properties only tools with very similar specifications — and even then very approximately.
Note that the same tool can work with batteries of different capacities — it is enough that they are compatible in terms of connectors and operating voltage. However, if you are looking for a spare battery or a replacement for a failed battery, it is best to choose a variant of the same capacity as the original one.

Battery model
The model of a standard battery allows you to find out its characteristics in more detail, and also helps you understand what devices it is like and which one should be purchased in case of a replacement due to a malfunction or, if necessary, buy another similar one.
Compatible batteries
Battery models compatible with the tool.
When choosing a tool, this information is relevant mainly for models without a battery in the kit (see "Complete battery"). For tools that come with batteries, the battery model is more of a reference—it's mostly "for the future" if a spare or replacement battery is needed. However, this data can also be useful in the selection process - for example, to assess compatibility with an existing battery on the farm, or to find detailed data on compatible batteries and determine how they meet your requirements (in particular, there are formulas that allow you to determine the time of continuous operation from a specific battery; these formulas can be found in special sources).

Charging time
The time to fully charge the battery that the tool is equipped with from a standard charger (when using other batteries or a “non-original” charger, this time may vary both in one direction and in the other).
For battery tools in general, see "Power source". And charging time data gives you an idea of how you'll need to organize your workflow and how long breaks you'll need to charge your batteries. The specific duration of the process will depend both on the capacity of the battery (all else being equal, a more capacious model takes longer to charge), and on the technologies used by the manufacturer to increase charging efficiency.
Also note that the specific meaning of this parameter also depends on the number of batteries in the kit. Recall that there are often several of them at once (see "Batteries in set"), and while one battery is working, the rest can be charged. This allows you to reduce interruptions to a minimum, and even completely do without them. But if there is only one battery, charging breaks will inevitably be required in full. This is especially true for tools with a built-in power source (in models with replaceable batteries, the situation can be corrected by purchasing additional batteries).

Charging connector
The presence in the cordless tool (see "Power source") of a standard USB connector for charging.
This feature is found mainly in low-power models with non-removable batteries (see "Complete battery"). Such a tool is usually equipped with an adapter cable from the charging connector to a standard USB. This allows you to use not only a standard device for such a battery, but also many other accessories - chargers for smartphones, tablets and other gadgets, universal adapters for sockets and car cigarette lighters, USB connectors on computers, laptops and other equipment, portable Power bank batteries, etc. P.

Charge level indicator
An indicator that signals the battery level in the corresponding tool (see "Power supply").
The device and capabilities of such a pointer can be different - from an LED "light" that gives the simplest signals by changing colour and / or blinking frequency, to detailed data on the instrument's own display. However, anyway, the charge level indicator makes it easier to monitor the state of the battery and reduces the likelihood of being with an “empty” battery at the wrong time.

However, anyway, the charge level indicator makes it easier to monitor the state of the battery and reduces the likelihood of being with an “empty” battery at the wrong time.
Battery mount
— Clip. With this fixation, the battery is fully or partially inserted into the handle of the tool - like a clip (magazine) of a pistol, hence the name. This method is convenient in that when installing the battery, there is a minimum of unnecessary parts outside; and small low-power batteries can completely hide inside the case without affecting the dimensions of the tool. On the other hand, for powerful and capacious power supplies with significant dimensions and weight, the clip-on mounting method is poorly suited for a number of reasons. Therefore, this option is found much less often than sliders, and mainly among low-power instruments.
— Slider. This method involves the use of special guides - a kind of "sled" along which the battery moves during installation and removal; such "sledges" are usually placed at the bottom, at the end of the handle. The slider is suitable for batteries of almost any size and weight, including the most powerful and heavy batteries used in power tools. In addition, it does not have such severe restrictions on the shape of the battery as a clip-type mount. So most modern cordless tools use sliders, and for medium and high power units, this option is almost standard. Its disadvantages include perhaps the moment that the installed battery is located outside the tool and somewhat increases its dimensions. However, this point most often turns out to be unprincipled - e...specially for powerful and heavy devices that are initially quite large.

Charger
A device for charging the batteries used in the tool with the appropriate power supply. For models supplied with such a device, the charger model may be additionally specified in the characteristics. This information can be useful not only for finding a spare or replacement charger, but also in case the household has other cordless tools and / or batteries for them. The fact is that many manufacturers nowadays use universal batteries that are compatible with a whole set of tools from the same brand; so, for example, a complete charger may be quite suitable for a cordless grinder or drill from the same manufacturer.
On the other hand, a lot of modern cordless tools come without a charger at all. This option will be optimal, first of all, if a compatible memory is already available, and there is simply no need to overpay for a second device. In addition, the lack of a charger will be appreciated by those who want to choose this accessory separately, without relying on the manufacturer's decision.

Depth gauge
The presence of a depth limiter in the design of the tool.
Such a device allows you to control the depth of penetration of the working nozzle when drilling or sawing. The design of the limiter may be different, however, anyway, it prevents immersion in the material to a greater depth than the specified one. This greatly facilitates the work: firstly, the risk of making a cut too deep or a hole is minimized; secondly, with an optimally set limiter, there is no need to regularly measure the depth — to obtain the desired cut or hole, it is enough to immerse the nozzle “up to the stop”.

Additional handle
The presence of an additional handle in the design or delivery set of the tool (it can be either built-in or removable).
This handle makes it easier to hold the tool with two hands, which is important when processing hard materials that require significant effort — or in delicate work, where precision and maximum control are important. Note that, as a standard, it is done based on right-handed users, however, many tools allow you to change the location of the handle, for the convenience of "left-handed" work.

Case (bag)
The presence of a case or cover in the tool kit.
A case is a hard container, a cover is a soft one; the main differences between them are due to this difference in materials. However, the purpose of both devices is the same: they provide ease of storage and transportation. This convenience is provided both by additional protection (in the case of covers — from dirt, in the case of cases — also from hits and shocks), and by the fact that all attachments and additional accessories, usually, are placed inside the cover/case, thereby reducing the risk of losing any of these items.

Flexible shaft
The flexible shaft is a special kind of accessory attachment supplied with the rotary engraver (see "Device") – this feature is not found in other tools. Outwardly, this device looks like a hose, sometimes quite long. One end of such a "hose" is attached to the engraver cartridge, and the other has its own cartridge, where the operating attachment is attached - rotation is transmitted to it due to the shaft located inside the "hose". The part of the flexible shaft held in the hands during operation is more compact and lighter than the engraver itself, so the most popular ways to use such equipment are processing hard-to-reach places (where the tool simply cannot crawl through) and fine work (which is difficult to do with a massive machine).
Tripod
A tripod is included with the instrument.
This function is found mainly among rotary engravers (see "Device"). The tripod is designed to hang the tool on it when working with a flexible shaft (see "Attachments") — usually, this is more convenient than simply placing the machine on a table or other surface. Without a tripod, this would have to use carnations, hooks or other similar devices — and they are far from being available everywhere, and they do not always provide reliable placement.

Pedal
An outrigger pedal is found among professional-grade suspended electric engravers. Its presence frees the hands of the master and allows you to adjust the speed of rotation of the nozzle by changing the pressure on the pedal. The dependence here is directly proportional - the stronger the pressure, the higher the speed.
Noise level
The noise level produced by the tool during operation. For comparison, 50 decibels roughly corresponds to the noise in an office room, 60 dB to an average TV volume, 70 dB to a truck at a distance of about 8 m, 80 dB to traffic noise, 90 dB to a loud scream.
The lower the noise level, the more comfortable the use of the tool. At the same time, note that this parameter is usually indicated very approximately — the actual “loudness” of operation can vary markedly depending on the mode, the nozzle used, the material being processed, etc.

Power cord length
The length of the network cable can tell you how far from the outlet you can operate the device. Therefore, for domestic use, it is more relevant to choose models with a short cord, for construction work or use in production, in the garage a longer cable is better.
Weight
The weight of the tool can be indicated according to different rules: some manufacturers take into account only the body without a nozzle, others — with a standard working nozzle, for multi-tools (see "Device") the weight of the main unit without a replaceable head, etc. can be indicated. These points are usually specified in the specifications or detailed documentation.
In the case of a power tool, weight has a dual meaning. On the one hand, the smaller it is, the easier it is to hold the unit in your hands during long work and the more convenient it is to carry out fine, accurate processing. On the other hand, a light tool is less stable and has an increased tendency to jerk, which is important under difficult conditions and hard materials.
