Round-Shank Masonry Drill Bits for Tapping Screw Installation
Each bit is precisely sized to match the tolerances necessary to achieve maximum holding strength from tapping screws. Use with handheld power drills, drill presses, and hammer drills. The shank has a tang which allows it to fit into a drill press with a tapered spindle.
