Cordless drill screwdriver is one of the most popular types of power tools, as it is super versatile. The device is able to perform both the functions of a conventional drill due to the high torque, and can also be used to tighten nuts and screws (like a classic screwdriver). For this, the drill / driver is equipped with a coupling for switching the magnitude of the torque. This allows you to increase the front of the work, from the usual twisting of screws into a drywall, to drilling holes in a concrete wall.
The presence of a battery positively affects the usability of the tool. It can be used where there is no outlet or when the work involves frequent movement of the master (the wires are constantly tangled under your feet or the length of the power cord is not enough). However, you should be aware of the downsides of batteries. Firstly, they require recharging, although in most models two batteries are included. Secondly, cordless drills. screwdrivers are somewhat more expensive than network ones. Thirdly, the batteries themselves are consumables, and sooner or later they fail and require replacement (depending on the intensity of operation).
If we compare a conventional screwdriver with a drill. screwdriver, then the latter wins in universality due to the function of the drill. But loses in ergonomics and usability, due to the greater mass.
You should also be aware of the key parameters of a drill / driver that you should pay attention to when choosing:
- Battery capacity. For household needs and rare use, a tool with a battery capacity in the range of 1.2-1.5 A / h, capable of providing a charge for two to three hours, is suitable. In the case of buying a drill / driver for a full-fledged workshop and frequent use, preference should be given to more "capacious" models.
- Supply voltage. This parameter determines the amount of torque on the spindle. Simply put, the higher the supply voltage, the easier it is for the machine to drill holes and screw in larger screws. For home use, a drill / driver with a 12-14 V battery is ideal.
- The maximum number of revolutions. The number of revolutions per minute characterizes the ability of the tool to screw in screws (or drill holes) of a certain diameter. Since at home, work is most often found with medium sizes (6-12 mm), then two speeds and 1200-1500 rpm will be quite enough.
- Torque. Key feature showing the “strength” of the tool. The larger this parameter, the higher the ability of a drill / driver to drill large holes and solid materials.
- Cartridge device. Since no one wants to suffer from equipment, the screwdriver with a one-jaw chuck will be the best choice for purchase. It is extremely easy to use and has a higher degree of reliability (due to fewer components).
- Optional solutions. If ergonomic parameters play a key role for you, pay attention to such additional elements as a second handle, the presence of a punch function, an angled nozzle for setting drill bits and bits, as well as an extended set of equipment. With them, a modest tool can turn into a multifunctional device for performing professional-level work.
Video: Network Screwdriver Which Is The Best Of Inexpensive Rating
We bring to your attention the TOP of the best cordless drills. screwdrivers in the categories: lightweight, inexpensive and professional models.
The lightest cordless drill / driver
The weight of the screwdriver is an important parameter, especially for those who often have to use the tool. For example, furniture assemblers, repairmen. The lighter the screwdriver. the less tired the hand (especially the wrist joint) gets tired and the easier and more comfortable it is to work.
As a rule, the lightest models are those that are equipped with lithium-ion batteries (Li-Ion). With the same dimensions as the nickel-based acb, Li-Ion has a higher energy density. Hence, it is possible to use a lower battery weight without reducing the tool life. Do not forget about another important plus of Li-Ion batteries. they do not have a memory effect, which means that you do not need to wait until the battery is fully discharged before recharging (as is the case with Ni-Cd and Ni-MH batteries).
Light screwdrivers are a tool for professionals in their field. We offer you to get acquainted with the three best cordless drill / drivers in the lightweight "weight category".
3 Hitachi DS10DAL
An inexpensive version of the Hitachi hammerless drill / driver, whose weight is only one kilogram. Despite this, the performance remains at a very high level: the keyless chuck is able to work with drills with a diameter of 0.8 to 10 millimeters (for metal), idle speed in the peak can reach 1300 rpm, and the torque on the spindle can increase up to up to 36 Nm.
2 Makita DF330DWE
The next place in the rating is the development of Japanese designers, the Makita DF330DWE hammerless drill / driver. Makita is considered one of the most popular brands of power tools. The quality and reliability of the Makita tool has been proven by millions of users worldwide.
Model Makita DF330DWE is one of the most successful in the company’s lineup. In our TOP-3. this is the best cordless screwdriver in terms of battery charge rate. From “zero” to a full charge, only 30 minutes pass. However, in terms of power, the model is slightly inferior to the leader, showing a maximum torque of 24 N · m. The device is sold in a very convenient and cute case. It is small in size, while everything you need fits without problems.
A distinctive feature of the model is a unique attenuation system of the LED working area. After releasing the trigger, the LED does not go out immediately, but gradually. Two Li-Ion batteries with a capacity of 1.3 Ah are supplied.
Advantages: lightweight, reliable, convenient case, excellent design, capacious batteries, fast battery charge, backlight
Disadvantages: not powerful enough, low quality cartridge, there is play
