Cordless screwdriver Makita 8281DWPE

The tool is powered by a new generation Li-Ion battery with a voltage of 14.4 V, which is undoubtedly its advantage.

The instrument is supplied with 2 rechargeable batteries and a charger that restores the instrument to function in just one hour. The rotational speed of the screwdriver is divided into 2 ranges: the first range of speeds includes values ​​of the rotational speed from 0 to 400 rpm, and the second range from 0 to 1300 rpm.

The screwdriver is equipped with a keyless chuck (10 mm), equipped with 16 steps of setting the torque (maximum value 36 Nm), and the weight of the tool is 1.7 kg. In addition to typical operations, the tool is equipped with an impact option, and is able to perform from 0 to 18 thousand impacts per minute.

As disadvantages of the tool you can specify the following:

  • For a tool equipped with an impact function, the manufacturer has provided it with a fairly weak chuck
  • Low battery capacity (only 1.3 Ah), which is not enough for intensive work
  • There is a possibility that the hand may overlap the ventilation openings for cooling the motor during impact operation, and the ventilation openings are so poorly positioned that they will overlap in the case of wide palms of the user
  • The gearbox housing of a screwdriver equipped with an impact function is preferably made of metal.

Overview of professional screwdrivers

A rational approach that allows you to save money was demonstrated by the BOSCH company, which released a model line of tools powered by a battery of a GSR 18 VE-2-LI Professional screwdriver. It should be noted that the cost savings are quite significant considering the high cost of a modern Li-Ion battery. Thus, by purchasing an additional tool from this company, there is no longer any need to purchase a battery.

The instrument is made with a somewhat exotic appearance. This design is not accidental. Firstly, it is simply not economically feasible to forge a tool body, and, secondly, exotic linings protect the tool from falling. In addition, the pads also provide the necessary ergonomics for the screwdriver handle (the user’s hand is protected from vibrations and does not sweat during intensive work).

The delivery set of the screwdriver includes a flashlight, a charger that ensures the restoration of the product’s performance in 1 hour and a battery with a capacity of 1.4 Ah.

The screwdriver has 2 ranges of speeds: the first range of speeds includes values ​​of rotation frequency from 0 to 300 rpm, and the second range from 0 to 1100 rpm.

The screwdriver is equipped with a keyless chuck (10 mm) and 22 torque settings.

When choosing, pay attention to the main disadvantages of the tool:

  • A morally outdated, albeit very reliable drill chuck
  • Unsuccessful attachment of the removable bit to the bracket (the bit often clings to clothing)
  • Small size of the reverse button, although its location is quite convenient for the user

All about battery-powered screwdrivers: pros and cons

The main difference between the cordless screwdriver and the network model is the absence of a cord. Autonomy of work and non-attachment to an outlet are the main advantages of a tool with a battery inside.

The advantages of the device also include:

  • Mobility. The tool and the charging battery are in the same housing, no additional elements are needed for operation. It is enough to take the device in hand, and it is already ready to work. Can be transferred to any location.
  • Compactness. Typically, household autonomous screwdrivers are small in size. This makes the device especially convenient in hard-to-reach places.
  • Universality. Technique replaces screwdriver and drill.

In practice, a cordless instrument is indispensable in objects without electricity, when it is necessary to frequently move or climb to a height. The device can be operated outdoors or indoors.

The only drawback here is the need to periodically charge the battery. Manufacturers are trying to solve this problem in every possible way, for example, offering 2 batteries with the tool. While one is in the working process, the second restores energy.

Manufacturer focus

A hackneyed truth – a brand beyond competition. Yes, branded tools are more expensive, but they have a quality guarantee and service centers for repairs, and the screwdrivers themselves are made of durable components.

Quite good screwdrivers with a removable battery are also offered by Varo Kreator, Sparky, Dnipro-M and others.

Torque

The numbers in the characteristic show with what force the screwdriver twists the self-tapping screw or how much force is required to overcome the load during drilling. What is the practical use of knowing the parameter? The diameter and length of the bolt to be screwed in depends on the torque. The higher the indicator, the longer and thicker the screws can be used in work without fear of failures or breakdowns. For example, at 40 N / m, it will be possible to freely "drive" a self-tapping screw 10 cm long into the tree.

In small household models, the torque is from 10 to 30 N / m, but the indicator can be adjusted by adjusting to the nozzle. For adjustment, a limiter is provided on the screwdriver body – a ring that goes immediately after the chuck. The user can coordinate the effort for a specific screw by scrolling the limiter. Result: as soon as the self-tapping screw is tightened to the desired level, the chuck will stop, although the motor will still work.

Interesting: The stop not only helps to tighten the bolts, preventing excessive “sinking” into the material, but also protects the tool from wear.

Makita screwdrivers

Second on the list is Makita, a Japanese company that has been making professional construction tools for 60 years. The range of the company includes both cordless and cordless Makita screwdrivers, coping with tasks such as:

1. Tightening screws, self-tapping screws and nuts into wooden structures;
2. Drilling holes in wooden surfaces;
3. Installation of plasterboard structures.

In addition to the standard models, those who make the Makita screwdriver offer a range of devices equipped with an impact function. If the idle speed of the shockless device reaches 2300 rpm, the impact drivers reach speeds of up to 3200 rpm. With this strength, the tool works well even on stone and iron surfaces.

With their small size and ergonomic appearance, the company’s screwdrivers operate at high power, reaching high values ​​of torque and working speed. The result is a perceptible vibration that even the ergonomic handle does not completely contain. Despite this, the company’s devices remain one of the most convenient on the market thanks to the rubberized handles and LED backlighting.

The Achilles’ heel of Makita devices is a weak battery that needs frequent recharging. Experienced craftsmen advise buying the best network models (such as FS4000 or FS2700), as for a modest surcharge, they significantly reduce time costs. However, if a screwdriver is needed not for professional purposes, but for home fastening work. It is not that important.

Bosch screwdrivers

If you want to distinguish between devices for household and industrial use. You can easily distinguish them by their color. Household tools are green when professional appliances are blue. Although Bosch tools remain among the most expensive on the market, the difference in price is more than offset by high quality standards and ease of use.

In addition to the basic device, customers receive a selection of different bits and tips to fit all the screws they need. Therefore, whatever the task of fastening is not faced by the master. Bosch devices help you cope with it.

Sparky screwdrivers

The fourth position in the list is occupied by Sparky Bulgarian screwdrivers. An experienced craftsman will distinguish them from afar thanks to the inherent red and black colors of the company’s models and an ergonomic shape that makes it possible to work in the most inaccessible places.

Despite the low prices, Bulgarian screwdrivers are not inferior to German and Japanese competitors in terms of safety and quality standards. Experienced craftsmen highlight a number of design features that make fastening work an order of magnitude easier and more comfortable:

1.Possibility without tool replacement of the nozzle thanks to the keyless chuck;
2. Light weight, ergonomic design and compact size, increasing the range of applicability of the device;
3. The ability to adjust the torque, an order of magnitude higher than the accuracy of work;
4. LED illumination, giving work in low light conditions;

If you want fast discharging batteries not to limit the operating time, the devices use a pair of lithium-ion batteries at once. When one battery is dead. It should be put on charge, quickly replaced with a second one. The device is equipped with energy indicators, so a discharged battery will not be a surprise to the master. So the work with the screwdriver will be continuous.
