Westward SDS Plus Rotary Hammer Drill, 3/8 in Drill Bit Size, 12 in Overall Length, 10 in Max Drilling Depth, Carbide Tipped

These drill bits have a carbide tip with multiple cutters for creating holes in concrete and masonry. The bits' SDS-Plus shank prevents them from slipping in high-torque drilling applications. The bits install into rotary hammer drills 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.
