Cordless Impact Drill GSB 18V-90 C. The GSB 18V-90 C Professional is a powerful cordless impact drill featuring a brushless motor that delivers a maximum performance of 64 Nm and 2,100 min⁻¹. Its compact head length of 175 mm ensures perfect handling. The robust 13-mm metal chuck guarantees excellent torque transfer for every job. The impact drill allows for outstanding tool control, enhancing both user and tool protection: the HMI offers an adjustable KickBack Control function that reduces the risk of kickback in the event of tool binding and sudden tool rotation. The adjustable Precision Clutch function prevents over-torquing once the preset torque is reached, thereby reducing clutch wear and noise generation. This tool is designed for drilling in wood with a maximum diameter of 68 mm, as well as in steel and masonry with diameters of up to 13 mm each. The GSB 18V-90 C Professional is compatible with all Bosch Professional 18V batteries and chargers.
