Bosch GSB 18V-55 Professional Cordless Brushless Impact Combi Drill 18V (Bare Unit)

The Bosch GSB 18V-55 Professional Combi Drill (Bare Unit) is a cordless 18 V power tool designed for screwdriving, standard drilling, and hammer drilling. It uses a brushless motor to deliver consistent performance in wood, metal, and masonry. A reversible drive lets operators install and remove fasteners up to 10 mm in diameter. Speed is controlled through the trigger, allowing adjustment to suit the resistance of different materials. As a bare unit, it is supplied without a battery, charger, or drill bits; users must provide compatible 18 V lithium-ion components. This setup suits tradespeople or regular users who already have batteries on this platform.

The front of the combi drill features a metal keyless chuck for quick, tool-free accessory changes. Electronic Motor Protection (EMP) guards the internal circuitry against overloading during heavy-duty work. The pistol-grip handle has a soft coating to maintain grip over extended use. A built-in light comes on during operation to illuminate poorly lit work areas. The chuck holds bits securely by internal friction, so no chuck key is needed. Transport and storage are handled by the included carrying case, which protects the tool between job sites.
