A powerful 550 W motor drives the pneumatic hammer mechanism from Bosch, delivering a high impact force of 1.7 Joules. An SDS plus chuck allows for quick, secure, and tool-free accessory changes. For the chiseling function with Vario Lock, you can choose from 36 chisel positions, ensuring an optimal working angle at all times. The hammer drill is also equipped with Bosch's electronic speed control, which makes it easy to adjust the right speed via the throttle switch to suit the material being worked on.
