The Bosch SDS-plus(R) hammer drill offers an exceptional weight/performance ratio for laying anchors in concrete, drilling in masonry, coring, and chiselling. This rotary hammer is extremely powerful, featuring 1.3 ft-lb of punching energy and a rated idling frequency of 0 to 5,850 BPM. It offers 3 modes of operation: piercing with percussion, piercing without percussion and perforation only. This drill is compatible with Bosch PRO + GUARD(TM) solutions: a complete suction system that helps users comply with OSHA's Table 1 regulations for silica dust. In addition to the low weight of just 5.7 lb (tool alone, without battery), it features an ergonomic design and a soft non-slip grip for added manoeuvrability.
