Dexter screwdrivers: characteristics, varieties, features of choice and application

Almost every man has a screwdriver in his toolbox. The tool is indispensable not only when performing repair work, but at any time it can be useful for solving everyday problems. In some cases, another similar device is more needed - a screwdriver.

A screwdriver is a tool similar in principle to a screwdriver, but has some differences. In general, both the screwdriver and the screwdriver are intended for screwing or unscrewing various fasteners, therefore, they have the same principle of operation. However, the main difference is that the screwdriver has a keyless chuck, which fixes both drills and bits. While the chuck of the screwdriver is not able to hold the drill.

Both tools have a number of advantages and the choice of either of them depends on what kind of work needs to be done.

The advantages of the screwdriver are as follows.

• More efficient with long and large self-tapping screws.
• Has a high speed of screwing screws into wood.
• The electric option is more economical in terms of energy consumption.

Benefits of a screwdriver:

• universal and allows you to fix not only bits, but also a drill;
• has several speeds.

On the market, these are represented by different brands, but recently the attention of buyers has been attracted by the Dexter screwdriver.

Under the Dexter Power brand, the Leroy Merlin brand has released a number of power tools, in particular the Dexter screwdriver. This tool is used to perform various assembly work.

The device has many functions necessary for this.

• The Dexter screwdriver is convenient to use in work due to its low weight - about 3 kg. It does not require great effort when working with it, since the device can be held with one hand.
• The tool is compact enough and does not take up much space.
• The screwdriver body is assembled with high quality, due to which the vibration of the tool is minimized at all available rotation speeds.
• It is characterized by an easy replacement of modules, including batteries, cartridges, and so on.
• You can reconfigure the screwdriver at any time. This manipulation will not take more than two minutes.
• The assembly uses a quick-release double sleeve chuck. Its diameter is up to 13 mm. The chuck can be easily removed from the tool by pressing the button on the body. The cartridge is also easy to put back on, as there are automatic fasteners.
• The instruments have ventilation openings to protect the instrument from overheating.
• The handles of the screwdrivers are equipped with rubber pads that prevent the tool from slipping in the hand and allow complete control of the workflow.

In the models of the Dexter screwdriver, you can find both a power tool and a cordless one. The kit mainly uses a lithium battery, which provides the tool with about 4 hours of operation and is the most modern source of energy.

The advantages of such batteries are as follows:

• there is no memory effect of batteries, that is, they can be recharged at any degree of discharge, except for zero;
• have a high charging speed - within one hour from the moment of connecting to the power supply;
• have a higher number of charge cycles than, for example, nickel-cadmium media.

As a disadvantage of these batteries, one can single out the impossibility to trace the degree of battery discharge, since it will no longer be possible to charge it from "zero". In this regard, more expensive screwdrivers have battery discharge indicators.

The most popular lithium battery powered Dexter screwdrivers today are the Dexter 18V and Dexter 12V screwdrivers.

This version of the screwdriver is the most profitable in its segment due to the good price-quality ratio of the product. The cost of the tool is about 5 thousand rubles. In this case, the unit operates on an 18 volt lithium battery and has 15 rotation modes. The tool battery takes 80 minutes to charge.

The technical characteristics of the screwdriver include the rotational speed, which in this model is represented by two speeds - 400 and 1500 rpm. And the torque of the screwdriver is maximum 40 N * m and has 16 adjustment positions.

The maximum drill diameter of the Dexter 18V screwdriver is 35 mm for wood and 10 mm for metal. The undoubted advantage of the model is the presence of reverse, that is, reverse rotation. The screwdriver of this model weighs about 3 kg.

The kit includes:

• 1 battery;
• Charger;
• belt clip;
• two-way bit.

This version of the Dexter screwdriver belongs to the more budgetary ones. Its price is about 4 thousand rubles. The unit has two modes of rotation - at 400 and 1300 rpm, and its torque is a maximum of 12 N * m and has 16 adjustment positions.

The tool runs on a 12 volt lithium battery, which charges in 30 minutes. The maximum drill diameter is 18 mm for wood and 8 mm for metal.

Like the Dexter 18V, the screwdriver has a reverse rotation (reverse). The Dexter 12V screwdriver is already a lighter tool - its weight is about 2 kg.

The completeness of this model is more modest than the previous one:

• 1 battery;
• Charger.

The screwdrivers are equipped with LED illumination, which makes it possible to work in low light. The special belt clip makes the screwdriver convenient for professional workers. In addition, some chargers can be fixed on a vertical surface using Velcro.

Dexter screwdrivers are used by both amateurs and professional craftsmen. Of course, some buyers have left reviews for this product.

Among the advantages of units, many consumers highlight the following factors.

• The tool is easy to carry with you, as well as to use in work due to its compactness.
• You can easily switch the rotational speed of the drill, since the control buttons of the device are conveniently located on its handle.
• A high-quality battery of the device not only slowly sits down, but also charges in 30 minutes. In this case, on a single charge with a screwdriver, you can work for several hours.
• It is easy to choose the optimal drill diameter and rotation speed due to their large number.
• You can work with any surface - both wood and metal.
• The cartridge can be easily removed and installed at the push of a button.
• The device has a stopper when not in operation. This is convenient for precision work and when removing the chuck.
• The reasonable price of Dexter brand tools makes them competitive in the market and attractive to users.

There are not many points to the disadvantages.

• Over time, the gripping force of the chuck may deteriorate, causing drills and bits to fall out of the chuck.
• Some consumers noted the wear of the rubber on the handle of the device as a disadvantage, which makes the tool unsuitable for constant work.
• In rare cases, the gearbox jammed on the tool, which had to be changed.

Based on the foregoing, the Dexter brand screwdrivers can be considered good "players" in the market, which have already proven themselves to be high-quality and reliable tools suitable for performing work of any complexity.
