Bosch Chisel Type Bull Point Chisel, Chisel Bit, 1/4", SDS Plus

These chisel bits have an SDS-Plus shank that prevents them from slipping in high-torque construction and demolition applications. They are used for breaking up concrete and prying and removing tile in one piece. The bits install into compatible rotary hammer drills and demolition hammers with SDS-Plus chucks, and they can be changed in the chucks with one hand. SDS-Plus chucks have spring-loaded balls that fit into the grooves on the bits' shanks to hold the bits in place in the chucks.
