    Carbide-Tipped Drill Bits for Masonry and Concrete

    Crush rather than cut material so bits don’t jam or overheat while drilling masonry and concrete. The ultra-hard carbide tip breaks masonry into pieces and the widely spaced flutes channel them out of the hole. These bits stay sharp, resisting wear and heat that will dull or break other bits.

    Shank

    The shank has 12 splines for use with a spline-drive rotary hammer, which rotate and hammers bits simultaneously to penetrate material. Also known as percussion or impact bits.

    Changeable-Size Carbide-Tipped Core Drill Bits for Masonry and Concrete

    Instead of investing in multiple bits, change the bit body to drill a different-sized hole. These hollow bits remove a large core of material from concrete, brick, and masonry for installing pipe and conduit. The carbide tip resists wear and heat to stay sharp. Bits include a pilot drill to make starting holes easier.
