DEWALT Stop Bit SDS Plus

SDS-Plus stop bits create holes for setting drop-in anchors in concrete and masonry. They have a built-in collar that prevents the bits from drilling past a specific depth, which allows multiple holes of the same depth to be drilled faster and more accurately than if using other types of concrete and masonry drill bits. The bits have an SDS-Plus shank that prevents them from slipping in high-torque drilling applications. They 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.
