45L291 Rotary Drill & Hammer Drill Bits

Bulk orders will be discounted, please contact us.

The spline shank on these drill bits prevents them from slipping in high-torque drilling applications when creating holes in concrete and masonry. The bits install into rotary hammer drills with spline-drive chucks, which have 12 grooves that mesh with matching grooves on the bits' shanks to hold them in place in the chucks.
