Comparison Makita DF001DW vs Bosch IXO 5 06039A8020

Design describes the overall layout of the tool.

Nowadays, among drills and screwdrivers, you can find models with a pistol, angle, straight, combined pistol-angle, as well as an adjustable design. Here is a more detailed description of each option:

— Pistol. In models with this layout, the handle is perpendicular or almost perpendicular to the body, so that the tool is held in the hands similar to a pistol — hence the name. In general, the pistol design combines convenience, safety, practicality and low cost. Due to this, this option is the most common nowadays, it is widely used in all types of drills and similar tools (see "Device"). In fact, this is a traditional design for such units; other types of layout are used mainly in models designed for special conditions and/or with specific characteristics (see below for more details).

— Corner. The general shape of such tools resembles the letter G: a straight body of relatively large length, which also acts as a handle, and a cartridge bent 90 ° relative to the body. This design option is especially convenient when working in cramped conditions: with the help of an angled tool, you can get into narrow gaps that are inaccessible to traditional pistol-mounted units. On the other hand, the angular layout degrades accuracy somewhat;...it is also poorly suited for jobs that require strong pressure along the axis of rotation of the chuck.

— Direct. Tools of this design have an oblong body, part of which plays the role of a handle; and the axis of rotation of the cartridge in them coincides with the longitudinal axis of the body. This option can be found in two types of tools. The first is small low-power tools (mainly screwdrivers, screwdrivers and wrenches, as well as single models of drills, also characterized by low power). In such cases, a straight body is provided primarily for compactness — a pistol grip would increase the dimensions beyond reasonable limits. The second type of direct units is, on the contrary, separate professional drills with a diamond drilling function (see "Purpose"). Such drills are not designed to be held in hands and are used only with a stand (see "Complete set"); for this format of use, the direct layout is also optimal.

— Pistol / angle. In fact, they are tools of the pistol layout described above, which are supplied with an angular cartridge that allows you to turn the working nozzle 90 ° relative to the standard position. Thus, such models combine the capabilities of both layouts, while retaining the main advantages of a pistol design — convenience and reliability in holding. On the other hand, additional equipment affects the cost, and such versatility is not often required. So this option is not very popular.

— Adjustable. This category includes all models in which you can change the location of the cartridge and/or handle relative to the body. The most popular version of this design is the rotary handle, which allows you to switch the tool from a pistol format to a straight one and vice versa. See above for more on these types of construction, but here we note that the pistol layout is more reliable in holding and versatile, and the straight one is better suited for some delicate work and hard-to-reach places. It is also worth mentioning that the possibilities for adjusting the handle can be different: in some models it has only two extreme positions, in others you can choose the angle of inclination relative to the body. The second, somewhat less common variety of adjustable tools is devices with a rotary chuck. Here we are already talking about switching between a straight and an angular layout — the latter, we recall, is very appropriate when working in cramped conditions. However, the cartridge in such units, usually, can be installed not only at 90 ° relative to the body, but also in several intermediate positions. This further expands the customization options for the specifics of the situation.
Anyway, all adjustable tools are more versatile than non-adjustable ones, but they are more complex in design and less reliable. Therefore, this type of arrangement is found exclusively in low-power units, mainly battery ones (see "Power supply").

The speed of rotation of the working nozzle provided by the tool.

If a single number is indicated in this paragraph (for example, 1800), it can be either a standard, constant, or maximum rotation speed. This refers to the maximum speed if the tool has more than one speed (see "Number of speeds") and/or a speed controller (see "Functions"). In turn, two or three numbers through an oblique line (for example, 1100/2300/3400) are indicated only for models that have the corresponding number of individual speeds. Each of these numbers indicates the standard (and in the presence of a speed controller — the maximum) number of revolutions at one of the speeds.

Anyway, when choosing a tool by the number of revolutions, it is worth considering both its general type (see "Device") and the specifics of the intended work. Detailed recommendations on this matter are quite extensive, it makes no sense to give them in full here — it is better to turn to special sources. We note only a few general points. So, high -speed drills nowadays are considered to be drills capable of delivering more than 3000 rpm. In general, high speed contributes to productivity, but there is also a downside: increasing the speed (for the same power) reduces torque — accordingly, the efficiency of working with stubborn materials and large diameter nozzles decreases. Therefore, it makes sense to specifically look for a "high-speed" tool only if speed is of key impor...tance; it doesn’t hurt to make sure that the model you choose can provide the required efficiency and torque.

Type of reverse provided in the design of the tool.

The reverse allows you to switch the direction of rotation of the nozzle; see "Functions" for details. It also indicates the type of switch responsible for this function. The varieties of such switches nowadays are very diverse: slider, flag, brush on the engine, on the start button, gyroscopic, on the keyboard toggle switch, and also combined with a flow switch or ratchet mechanism. Here is a detailed description of each of these varieties:

— Crawler. Switch in the form of a slider with two opposite positions. Usually, it moves in the direction "back and forth" relative to the tool chuck — this format is considered the most practical. The sliders are quite simple and at the same time convenient and visual, especially when used in screwdrivers and wrenches: by moving forward (away from you), the direction of rotation is set to twisting, by moving backward (toward yourself), respectively, to unscrewing. However, such devices are widely used in other types of instruments (see "Device") and are generally the most popular option nowadays.

— Combined with the flow switch. The most popular type of reve...rse in pneumatic tools (see "Power Source"); not found in other models. The flow switch itself is actually a speed controller, most often in the form of a distinctive rotary knob or lever. And if this regulator is combined with a reverse, this means that it can deviate from the neutral position in two directions, and the direction of rotation will depend on which direction the flow switch is shifted.

— Flag. A switch in the form of a flag, usually installed above the start button and thrown to the right and left. One of the advantages of a checkbox is that it is right at your fingertips and can be toggled with almost no unnecessary movement (which is not always available for a slider). On the other hand, this option is mainly suitable for drills, and in screwdrivers and wrenches, the checkbox is not as intuitive as the same slider. And in general, this type of reverse for a number of reasons is much less common.

— Brush (on the engine). Reverse switch installed directly in the tool motor and based on the use of a special movable brush holder. By changing the position of the brushes in the motor with the help of such a mechanism, it is possible to change the direction of its rotation. One of the key advantages of this method is that it allows you to achieve maximum power in any direction of rotation without any special tricks. In addition, such an adjustment has a positive effect on the engine resource. On the other hand, brush switches are quite complex and expensive, and therefore are installed mainly in a powerful professional tool.

— On the start button. Reverse switch combined with start button. Such a combination button is usually made in the form of a "rocker", and the direction of rotation depends on which side of the rocker the user pressed; pressing the same button immediately starts the engine. This design allows you to easily and quickly change the direction of rotation — for this you do not need to be distracted by individual switches, just move your finger slightly and press the other half of the start button. This is especially convenient for screw and wrench drivers, as well as screwdrivers; in fact, most of the models with this type of reverse belong to these types.

— On a keyboard switch. The control method, in many respects similar to the reverse on the start button described above, also uses a rocker switch. The key difference is that in this case the direction switch is made separately from the start button — that is, the user must first select the direction of movement, and then press "start". This option does not have any particular drawbacks, but it also does not differ in convenience, and therefore it is extremely rare.

— Gyroscopic. A rather rare and specific type of reverse, found exclusively in screwdrivers (see "Type"). In fact, there are no external switches in such a tool — instead, a built-in gyroscope is used to track body rotations. Accordingly, to select the direction of movement, you need to rather sharply turn the tool around the longitudinal axis in the appropriate direction and smoothly return it to its original position (speed can be adjusted in the same way — for example, the farther the turn, the higher the speed will be). This control method is very simple and intuitive, but it is rather complicated in technical implementation and requires increased accuracy in handling the tool. That is why gyroscopic reverse is extremely rare nowadays.

— Combined with a ratchet mechanism. Another rather rare option, found exclusively in wrenches — mostly pneumatic, less often battery-powered (see "Power"). The ratchet mechanism, we recall, is responsible for ensuring that the working part of the tool rotates in only one direction. And the reverse is controlled through a mechanical switch, which is directly connected to this mechanism and changes its settings, setting one or another direction of rotation.

The total weight of the tool is usually the device itself, without attachments. For battery models (see "Power Source"), usually, the weight is indicated with a standard battery installed; for battery-powered models, the weight can be given both with and without batteries, but in this case this point is not particularly important.

Other things being equal, less weight simplifies work, increases accuracy of movement and allows you to use the tool for longer without tiring. However, note that high power and productivity inevitably increase the mass of the tool; and various tricks to reduce weight increase the price and can reduce reliability. In addition, in some cases, a massive design is more preferable. First of all, this applies to work with a large load — for example, drilling holes of large diameter, or making recesses with impact: a heavy tool is more stable, it is less prone to jerks and shifts due to uneven material, vibration of mechanisms, etc.

It is also worth noting that specific weight values are directly related to the type of tool (see "Device"). Screwdrivers are the lightest — in most of them this figure does not exceed 500 g. Screwdrivers and drill drivers are more "heavy": their average weight is 1.1 – 1.5 kg, although there are many lighter ( 0.6 – 1 kg) and heavier ( 1.6 – 2 kg or more ) models. And clas...sic drills and wrenches have the greatest weight: such a tool must be quite powerful, so for them 1.6 – 2 kg is an average, 2.1 – 2.5 kg is above average, and many units weigh more than 2, 5 kg.

- Corner nozzle. A nozzle that allows you to rotate the axis of rotation of the cartridge by 90 ° relative to its original position. Such a device is indispensable for making holes, as well as twisting and unscrewing fasteners in some hard-to-reach places (for example, in narrow grooves or a profile).

- Eccentric nozzle. Replaceable nozzle designed to shift the axis of rotation of the cartridge slightly away from its original position. In this case, the direction of the axis remains the same. Like the corner nozzle, such a device is intended mainly for working in certain hard-to-reach places (in particular, near walls and edges of workpieces).

- Additional handle. A modern tool, even a relatively low-power one, can be quite massive, and for maximum accuracy and reliability it may be necessary to hold it with two hands at once. Using an additional handle for this is more convenient and safer than looking for a place to grip on the body. The handles themselves are usually mounted near the cartridge perpendicular to the axis of rotation and may have different design features.

- Depth stop. A device that allows you to limit the depth of drilling. The most popular version of such a limiter is a rod in a special mount, installed parallel to the drill. Before starting work, this rod is shifted so that when the desired depth is reached, its end rests on the surface of the material,...preventing the drill from moving further.

- Store nozzle. It looks like a kind of store or disk, into which a tape with self-tapping screws is “charged”; and a special block is installed in front of the cartridge, designed to supply self-tapping screws. This design allows you to tighten the screws as quickly as possible and without unnecessary movements: just load the tape from the magazine into the feed unit, start the engine and alternately press the working part of the tool to the desired points on the material.

- Lantern. A classic flashlight for illumination in low light conditions, in contrast to the built-in illumination system, is a separate device. Such a separate device is not very convenient to hold in your hand during work - in such cases you can’t take the tool with both hands, and this creates problems in some situations. On the other hand, often the situation allows you to put or hang a lantern without taking up your hands; and sometimes in this way you can even organize the lighting more successfully than using the built-in backlight. In addition, the flashlight can be used independently.

- Case (bag) included. The presence of a case or bag in the delivery set of the drill. Cases are usually called hard suitcases; bags, unlike cases, are soft, which allows them to be packed more tightly together with other things, but reduces the degree of protection. In any case, this feature makes the tool more convenient to store and carry: the complete bag or case is optimally suited for this model, in addition, they can hold drills, spare batteries and other additional accessories.

- Rack. Mostly professional drills for diamond drilling are completed with racks(see "Purpose"). This design is a stand (base) with a guide rail fixed on it, along which the tool can move using a special mechanism. According to the fastening of the rail, the racks are divided into two types:

• Non-inclined stand. A structure with a rigidly fixed rail, which is usually located vertically, perpendicular to the base; accordingly, the axis of rotation of the installed tool also remains always vertical. Such racks have more limited capabilities than inclined ones. On the other hand, they are simpler, cheaper and more reliable (there is no movable mount in the design that can become loose); and for most work, the vertical position of the tool is fine.
• Tilt stand. Stands in which the rail is fixed on a swivel mount and can deviate from the vertical at a certain angle. Accordingly, such a device allows you to direct the crown not only vertically, but also at an angle; this can be important for some non-standard tasks. On the other hand, a movable structure is more complex, expensive and less durable than a fixed one; therefore, it is worth paying attention to this option if the possibility of inclined drilling is fundamental for you.

- A set of drills. The presence of drills in the kit eliminates the need to purchase them separately and allows you to use a drill (or other tool with drill functions) right out of the box. True, the specific assortment of drills can be different - besides, it is often an entry-level set of 5 to 7 devices for the simplest tasks like drilling wood. However, even such a set will be useful if the tool is purchased for domestic use or simple work that does not require specialized nozzles. We also note that such equipment is especially convenient when buying a “first tool for a beginner”, when there are no drills on the farm yet and one way or another you will have to buy them.

- A set of bits. Bits, we recall, are nozzles in the form of screwdriver heads, which are also used in screwdrivers. As in the case of drills, the presence of such nozzles in the kit eliminates the need to purchase them separately and makes it possible to use the tool immediately after purchase. The specific set of bits is worth specifying further, but most often it includes at least flat and cross bits in a fairly large variety of sizes. And in general, such sets are quite extensive - even in relatively inexpensive tools, the number of complete bits can be measured in tens.

- Equipment. The term "equipment" means at least several types of working nozzles, and sometimes additional accessories. For example, if such equipment is indicated for a drill-driver, then this model is almost guaranteed to be equipped with both drills and bits (and possibly more specific accessories). A specific set of equipment should be specified separately.

- Extension. The purpose of such an accessory is clear from the name: it allows you to increase the working length of the tool. In other words, when you install an extension bat or other equipment, it is further from the body; the extension itself is made quite thin. This accessory is used mainly in models with the functions of a screwdriver or wrench: it allows you to reach deep-seated fasteners that are inaccessible in the usual configuration. And in many models, the extension cord is also made flexible, which further expands its capabilities.

- Magnetizer. Device for magnetizing bolts, screws and other similar fasteners. Found in individual screwdrivers; the working tooling of such tools is also made of magnetic material, due to which the magnetized fastener effectively “sticks” to the tooling and does not need to be supported separately.

- Case insert. Interchangeable insert (or several inserts) to adjust the complete case to the specific situation. For example, a regular insert can only have space for a tool and a charger, and a replacement one can also accommodate a second spare battery. Specific features should be specified separately.

- Charger(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 for a drill may be quite suitable for a cordless grinder 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.


Note that the above list is not complete - modern tools can be supplied with other additional items, including very unexpected and original ones - like a fitness tracker or even a radio-controlled car.

The time to fully charge the battery that the tool is equipped with from a standard charger (when using other batteries or a “non-native” charger, this time may vary both in one direction and in the other).

For cordless 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 (ceteris paribus, a more capacious model takes longer to charge), and on the technologies used by the manufacturer that increase charging efficiency. However, in general, it is customary to refer to tools with a good charging speed as models where this procedure takes no more than 45 minutes.

We 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 "Complete battery"), 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).
