55JD97 Rotary Drill & Hammer Drill Bits

Bulk orders will be discounted, please contact us.

These bits have a hollow shaft and dust-extraction holes at their tip that allow dust to be removed with a dust extractor during drilling. This reduces both the amount of dust that is released into the surrounding air during drilling and the amount of dust that must be cleaned out of the hole prior to setting the anchors. The bits have an SDS-Plus shank that prevents them from slipping in high-torque drilling applications when creating holes for setting concrete screw anchors. 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.
