Bosch Rotary Hammer SDS-Max 52mm 1700W GBH 12-52 D

The most heavy duty Bosch SDS Max rotary hammer on the market, the GBH 12 52 D has a powerful, high end motor which delivers 19J of impact energy for heavy chiselling and ultimate performance in all SDS Max applications. The user is safeguarded against the hazards of accessories jamming thanks to a Rotational Control clutch which minimizes torque without abrupt blockage in the event of overload or binding. Restart protection also ensures the machine cannot remain "on" in the event of a power cut or detached plug, and will not start up by itself if plugged into a live outlet. Model GBH 12 52 DV is the Vibration Control model which has additional rubber mountings and foam padding to absorb vibration travelling to the operator's hands.
