Brushless screwdriver with metal gear

Which screwdriver to choose

From the variety of tools available on the market, we can recommend brushless screwdrivers of the following Russian and foreign manufacturers: Metabo, Interskol, Bosh, Enkor, Hilti, Whirlwind, DeWalt, Ermak, Makita, Hitachi, Ridgid , AEG, GreenWorks, Black-Decker.

The choice of a specific manufacturer and its model of a screwdriver depends on the tasks that will be assigned to this tool and on the available budget.

According to the reviews of the majority of buyers in the Russian power tool market, brushless screwdrivers from such manufacturers as Bosch, Makita and Interskol are most trusted.

If the choice in favor of a brushless tool is obvious, then it is not so clear what kind of battery it should be equipped with. There are two recommendations here:

For regular professional use, rechargeable lithium-ion batteries are preferred. They allow an unlimited number of recharges, do not have the so-called "memory effect". Included with them is to purchase a reliable professional charger. Such batteries work exactly as long as prescribed in their warranty - about 4-5 years.
For rare amateur work, nickel-cadmium batteries or nickel-metal hydride batteries are more profitable. Over time x the resource is not wasted, it depends on the number of cycles of use. Another advantage, in addition to the budget price, is frost resistance.

When not using the screwdriver for a long time, store the tool with the battery disconnected. The optimum storage temperature is about 15 degrees Celsius. Away from heating appliances and sunlight. If an oxide film appears on the contact pads, then it must be removed with a solvent recommended by the manufacturer (in order to avoid damage to the instrument itself). These are usually ethyl alcohol-based formulations.

How to choose?

For effective work with a brushless screwdriver, you should take all the responsibility when choosing a model when buying. The store inspects the main characteristics of the instrument and other nuances:

Purpose of Acquisition. First, you need to decide what tasks you plan to perform with a brushless screwdriver. If it is purchased for professional needs, of course it is worth taking the most powerful and reliable tool. It will have a more capacious battery, additional functions and settings, and a wide range of options. If the tool is purchased for domestic use, you should not choose a professional expensive model, you can limit yourself to a simpler option.

Workpiece material

Here it is important to decide which surfaces the brushless screwdriver will contact with. For productive work with metal, a rotation speed of more than 1200 rpm is required (they are offered by professional tools)

When drilling wood, 400 revolutions of a household model will be enough.

Torque and operating voltage. In household models, these characteristics are at the level of 15-20 Nm and 9.6 V, and in professional models - 130 Nm and 12 V.

Cartridge. Models of brushless screwdrivers can be with two types of chucks (keyless and hex). The first type is compatible with accessories of any shape (hexagonal, cylindrical), and the second allows you to change the attachment much faster.

Reducer. This device transfers revolutions from the engine to the chuck, changing their torque. There is a metal or plastic gearbox, most often it is two-speed. For tightening the screws, a gearbox that produces 500 rpm is suitable, and when drilling, 1200-1300 rpm will be needed.

Convenience. There is no one-size-fits-all device that works equally well for every user. Here you should choose on the basis of personal comfort. When buying, you should hold the screwdriver in your hands, evaluate its weight and the location of the buttons, as well as the level of hand sliding.

Additional functions. A lever to select from multiple speeds will help you conserve battery power and find the right position for each material. The impact mode will help for working with bricks, the backlight will save you in a dark room, and the reverse mode will help when the nozzles get stuck and the fasteners are unscrewed. The complete set will allow you to choose the attachment for any occasion in a convenient case.

Brushless screwdrivers differ significantly from their counterparts with KSHU technology. They are more productive and durable, but less noisy and heavy. The main disadvantage of brushless screwdrivers is the high price, but when buying a professional tool that will last for many years, you have to sacrifice something.

The store pays attention to engine power, ease of use, additional functionality and the purpose of using the screwdriver

Makita brushless screwdriver: the Japanese leader

Models LXDT06, LXDT08 DF332DWAX1 are the real pride of the Japanese company. But first things first.

LXDT06 opens the rating of devices of the land of the rising sun. The unit with an 18-volt motor is characterized by the presence of a speed control switch, as well as three power levels and a system called Quick Shift, which allows you to make adjustments to the speed as quickly as possible.

Models of brushless screwdrivers LXDT06, LXDT08 DF332DWAX1 are the pride of the Japanese company Makita

Thus, you can start working at a higher speed, since there is simply no point in using another mode. By reducing the speed at the end, the likelihood of damage to the screw head, bit or part to be machined is significantly reduced.

The LXDT06 outperforms all existing brushless impact drivers in performance. Its advantage over the best models of competing companies is considered to be its shorter length.In addition, the device is endowed with a built-in flashlight, which perfectly illuminates the working area. It is positioned in such a way that the shadow cast by the tool is completely negligible. This significantly increases comfort and convenience during work.

Speaking of LXDT06, it is worth noting that the device is ergonomic and compact, due to which it fits perfectly in the hand. Despite the fact that its battery is not much larger than that of peers from other companies, it boasts a higher power, which means a longer battery life.

The DF332DWAX1 brushless screwdriver is a compact and quite powerful tool

If anyone has doubts about which is better - a brush or brushless screwdriver, the LXDT06 model will certainly dispel them. The impact unit is characterized by high power and compactness at the same time. There are no special innovations here, but they are not needed at all. The characteristics of this device will delight even professionals, not to mention amateurs who have more than enough power that this device has.

Compact and at the same time quite powerful - this is how the DF332DWAX1 can be characterized. The brushless screwdriver introduced by the Japanese company is an excellent solution for drilling wood and metal surfaces. Not too high voltage is more than compensated by the highest efficiency of the presented model.

The engine of the unit is manufactured in accordance with brushless technology, which guarantees power, serviceability and compactness. The presented device is equipped with two batteries, which are protected from overload and are equipped with a built-in indicator that displays the discharge.

Based on the characteristics described above, we can safely say that the Japanese company does not intend to give up its positions in the market for tools with brushless motors. It was she who began their implementation, after which she was the first to offer users a speed control system, and at the moment she is demonstrating a mechanism for automatic speed reduction.

LXDT06 is considered the best brushless impact driver

High power, quality and easy to use - it's all about the Makita brushless screwdriver. Such a tool will turn the execution of routine construction tasks into an easier and more efficient process.

Having precisely determined which is better - an impact or a shockless screwdriver, you can start the buying process

In this case, you should pay special attention to the additional functions offered by the manufacturer. It is better to make a choice in favor of a tool that assumes the ability to regulate not only the speed of rotation, but also its direction.

In addition to the optimal price-quality ratio of screwdrivers, their options are important, such as backlighting, an indicator that notifies about the charge level, as well as a number of other useful functions, thanks to which the operation becomes as comfortable as possible. And in the presence of a second battery, a case for convenient transportation, charging and a set of accessories, such a unit will certainly deserve the attention of users

Advantages and disadvantages of a power tool without brushes

Brushless screwdrivers have both advantages and disadvantages. Of the first, the following can be distinguished:

Great reliability and significant durability resource. This is clearly seen when compared with a similar tool with a collector motor. Most often, it is the brushes that break in it, but they are not in the brushless screwdriver.
Minimum noise level during tool operation. This is achieved by the fact that the brushes that produced a significant proportion of the noise are absent in the design.
High level of fire safety.With such a screwdriver, you can safely, without fear of a sudden fire or explosion, work in highly dusty rooms, or in those where flammable impurities are present in the air (for example, natural gas, fumes of hydrocarbons, alcohols, etc.). When working with a brushless motor, sparks are completely excluded, as in motors of old designs.
High torque in a relatively compact engine. This allows you to tackle heavier jobs with a highly mobile and easy-to-operate tool.

And what is important - without the risk of a reverse effect - it is he who is a frequent cause of injuries to the wrist ligaments and damage to consumables (due to thread breakdown, jamming or deformation of fasteners).
Longer battery life when using battery models. This is achieved by a very rational layout of the engine and its high efficiency - about 85-90%

Accordingly, the energy reserve in the accumulator is spent almost entirely on performing work, and not on overcoming friction, as in the case of collector motors.

There are only three disadvantages of brushless screwdrivers:

The high cost of the tool. This is the most serious drawback, as the instrument market is oversaturated with much cheaper instruments. It is able to recoup itself many times over long before failure. And its repair is simply not needed - it is enough to buy a new instrument for the same low price.
With high reliability of the engine, there is a problem of failure of other components - primarily the electronic part and, less often, the gearbox.

The gearbox needs regular lubrication. To do this, you need to familiarize yourself with the manufacturer's recommendations and strictly follow them. In general, you need to: - disassemble the gearbox,
- remove the remnants of the old grease,
- inspect the gears for possible damage (chips, abrasions),
- Apply a new lubricant in the required amount (this is usually a Teflon or silicone based lubricant).

Difficulty, and more often just the impossibility of self-repair. This is due to the complex microelectronic part of the instrument. If it is damaged, independent operational repair is almost impossible. And not many craftsmen will like this - they depend on expensive components and service centers.

Features of the device and principle of operation

Among the features of the tool, it is worth highlighting:

Convenient one-handed operation. To install self-tapping screws, the craftsmen do not need to hold them, since they are fed automatically along the tape to the place chosen for installation. It is enough to periodically press the trigger - the button.
Significant optimization of ceiling work. The master can already do without an assistant, independently hold the mounting light structures with his free hand, using a tape screwdriver, the battery-powered type of the tool is considered the most convenient when moving during the installation process, since there are no restrictions on the power cord.
Safety is increased. The handle of the tool is located outside the working part of the tool, therefore, the operation is not traumatic.
Convenient storage of fasteners. Self-tapping screws are installed on the feed belt, there is no need to constantly remove them, the risk of loss, spillage is reduced.

The device of such equipment contributes to high-quality and safe operation. Components of a tape screwdriver:

body made of aluminum or with the addition of plastic;
node designed to change the working "store";
nozzles for advancing fasteners in the tape;
locking base for fixing the heads of self-tapping screws;
rechargeable battery (in stand-alone tools);
a block designed to suspend a screwdriver;
auto-feed of fasteners with a narrowed outer diameter (for ease of installation in corner sections).

A tape is attached to the working part of the equipment, on which self-tapping screws are fixed. The bow of the structure is applied to the wall, the cable is pulled, the fasteners are fed to the places where they need to be installed. By pressing the installation button, the screws are twisted one by one.

By working on this principle, a large number of fasteners can be quickly installed. The tape contains about 50 of them. Screwdrivers with this feed are excellent for installation work with drywall.

A useful addition to the device is the reverse function. And by fixing the start button, the continuous operation of the tool is ensured.

Operational features and application

A high-quality screwdriver can be made with a permanently installed mechanism for feeding self-tapping screws. Such a unit cannot be used without a special equipped belt. The final calculation of the productivity of such equipment is quite understandable, because for each type of work its own unit must be used. There is another option, when specialists use a removable nozzle for a conventional screwdriver. Thanks to this, the device can be easily converted into a universal unit by quickly dismantling the top nozzle.

A multifunctional screwdriver with a tape feed of screws is most often referred to as professional devices, because it is not suitable for small household tasks. The cost of such a screwdriver is superior to similar models, which are intended for the implementation of home repair work. This is mainly due not only to the special feeding mechanism, but also to high strength and durability.

The principle of operation of the unit is quite simple, since it can be operated with one hand. The master will no longer need to take out a new self-tapping screw all the time, carefully push it onto the tip of the bit, holding and adjusting the tool for accurate direction. Now the master has an excellent opportunity to hold the material to be fixed with his free hand in order to attach it to the guide planes with a few precise strokes.
