The GSB 18V-90 C Professional is a powerful cordless impact drill with a brushless motor that delivers top performance with 64 Nm and 2,100 rpm. Its compact head length of 175 mm provides perfect tool handiness. The robust 13-mm metal chuck ensures great torque transfer for every job. The impact drill holds a very high level of tool control for both, increased user health and tool protection: The HMI offers switchable Kickback Control to reduce the risk of sudden rotational torque reaction in a bind-up scenario. A switchable Precision Clutch stops the overriding once a preset torque level is reached and, thus, reduces the wear and tear of the clutch and the resulting noise.
The tool is intended for drilling in wood with a maximum diameter of 68 mm and in steel and masonry with up to 13 mm each. The GSB 18V-90 C Professional is compatible with all Bosch Professional 18V batteries and chargers (Professional 18V System).
