The Bosch GSR 18V-90C Professional Drill Driver with a brushless motor delivers top performance. Its compact head length of 163mm provides perfect tool handiness. The robust 13mm metal chuck ensures great torque transfer for every job. This drill driver has a very high level of tool control for both, increased user health and tool protection. Switchable Kickback Control reduces the risk of sudden rotational torque reaction in a bind-up scenario. There is also a switchable Precision Clutch stopping the overriding once a preset torque level is reached and, thus, reduces the wear and tear of the clutch and the resulting noise. Compatible with all Bosch Professional 18V batteries, including ProCORE18V batteries and chargers (Professional 18V System). Also compatible with AMPShare, the multi-brand battery alliance.
