Cordless hammer drills

Impact drills are universal cordless power tools. We can drill them in construction and machinable materials and assemble / disassemble bolts, screws, etc.

Design of cordless hammer drills

Impact drill drivers have the following components: electric motor (2-pole, 4-pole or brushless), cooling fan, planetary gear (2-, 3- or 4-speed) with impact mechanism, setting ring for changing the torque for screwdriving and operating modes (hammer drilling, non-impact drilling, screwdriving), mechanical or electronic torque clutch, drill keyless chuck, spindle auto-lock, coasting brake, switch and electronic speed and torque control systems (incl. in the event of a drill jam), anti-overload for the motor and battery, optimizing energy consumption and protecting the cells against shortening the service life, right / left rotation slide switch, "T" housing with main handle and optional additional handle, battery mount, Li-Ion battery. In addition, some models are equipped with application control on mobile devices using Bluetooth technology. This application is also used to manage the operation of machines and contact the manufacturer and service.

Accessories for cordless impact drills

These devices use a wide variety of drilling tools: spiral, flat, step and percussion (widi) drills, countersinks, reamers, center and sedimenters, as well as hole saws, diamond bits and carbide teeth etc. Bits and sockets are used to perform screwdriving / unscrewing operations. We can use adapter adapters to mount them in the drill chuck. On some models, these accessories can also be mounted in a 1/4 "hexagonal socket in the spindle after removing the drill chuck.

Main technical parameters of cordless hammer drill / drivers

The technical parameters of the impact drill drivers are: supply voltage (10.8, 14.4, 18, 25.2 or 36 V), torque (max. 136 Nm), adjustable torque (1.2-7 Nm), number of gear ratios (2-4), idle speed (maximum 3800 / min), frequency of impacts (maximum 76,000 / min), maximum drilling diameter in steel (16 mm), maximum drilling diameter in wood (90 mm), maximum screw dimensions (10 x 300 mm) number of torque settings (maximum 24), machine weight (0.9-3.2 kg).

Applications of cordless hammer drills, their advantages and manufacturers

Percussion drills are very functional and universal power tools. They 100% replace classic hammer drills. Their important feature and advantage is the adjustable clutch that allows you to set the torque in the range of 1-7 Nm. Therefore, they guarantee high-quality assembly of screws and bolts, which cannot be said about hammer drills. Moreover, they are fully mobile and independent of network power sources. Cordless impact drills are made by AEG, Bosch, DeWALT, Fein, Festool, HiKOKI, Panasonic, Makita, Milwaukee, Metabo.
