Bosch recently introduced an upgraded version of its Bulldog rotary hammer, the Bulldog Xtreme Max (RH228VC). A precision-machined striker and an oversize piston and impact bolt make for an efficient transfer of energy that translates into greater power and speed – according to the maker, the new Bulldog delivers 20 percent more impact energy and drills up to 40 percent faster than competing models. Because it has a counterbalance, the Xtreme Max vibrates 30 percent less than key competitors, says the maker. This 8-amp tool has an integral clutch and three modes of operation: rotation only, rotary hammer, and hammer-only.
