The GSB 18V-90 C Professional is a powerful cordless hammer 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 transmission for every job. The hammer drill allows for outstanding tool control, providing 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.
