Comparison Tolsen T-300 (79558) vs Vitals Master AMi 1815Pq SmartLine

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.

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.

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.

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.

- 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.

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.

The type of power used by the tool to perform its work.

— Network. Power supply from a regular household 220 V network. This option allows you to create units of almost any power - within the limits of what can be useful for a hand tool. At the same time, such models, all other things being equal, weigh less and are cheaper than battery-powered ones, and when working with them, you do not need to monitor the battery condition, 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 increased caution (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 convenient to use — it does not require a connection to the network, which allows you to work even in the complete absence of sockets nearby. And the absence of a cable has a positive effect on convenience and safety. On the other hand, the power of battery-powered models is generally lower than that of network-powered 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 after the charge is exh...austed, the battery will have to be charged, which takes time and requires power supply. This drawback in some models is compensated for by the presence of a spare battery in the delivery set (see "Replaceable battery"), but only partly — the second battery increases autonomy, but does not eliminate the need to charge dead batteries. Taking all this into account, you should pay attention to models with such a power supply only if the ability to work without sockets is critical for you.

— Batteries. Models powered by replaceable AA batteries and some of its derivatives. This method of power supply is implemented in low-power tools like compact rotary engravers.

The number of batteries supplied with the respective tool (see "Power source"). This item may also indicate whether the tool has a built-in battery.

The most popular battery-powered kit option these days is 2 batteries. This provides additional benefits that are especially convenient for long-term continuous use of the tool. So, when one battery runs out of charge, you can quickly replace it with another; and while one battery is in use, the second can be charged. This allows you to minimize or even eliminate breaks for charging. Kits with one battery are not very common: these are mainly entry-level tools designed for small volumes of work, when breaks for charging are quite acceptable.

In addition, many modern cordless tools are supplied without batteries. This configuration assumes that the customer will purchase additional batteries at his own discretion (many models are compatible with several brands of power elements at once). In addition, this option may be useful if you already have a battery on hand. This happens quite often, since many well-known manufacturers use universal batteries suitable for different types of branded power tools. So, for example, a battery from a previously purchased jigsaw or grinder may well be compatible with an engraver or renovator from the same company.

As for non-removable batteries, this is a rather...rare and specific option. Such tools are as compact as possible, but the batteries themselves cannot be quickly changed - so during work you will inevitably have to take breaks for charging. Therefore, this power supply method is typical for low-power tools. In them, small dimensions are more important than a long period of continuous operation, in addition, low capacity allows you to achieve good autonomy even with small sizes (and, accordingly, capacity) of batteries.

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.
