Dewalt SDS Plus Rotary Hammer Drill Bit, 1/4 in Drill Bit Size, 12 in Overall Length, 10 in Max Drilling Depth, Carbide Tipped

The entire cutting head on these drill bits is made from solid carbide, which allows the bits to last longer than standard SDS-Max concrete and masonry drill bits. The bits' SDS-Plus shank prevents them from slipping in high-torque drilling applications when creating holes in concrete and masonry. 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.
