    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.

    SDS-Plus

    Shank

    The slotted shank fits SDS-Plus-drive rotary hammers, which rotate and hammer bits simultaneously to penetrate material. Also known as percussion or impact bits.

    Hex Shank for Rotary Only Drilling
    Image of Product. Side1 orientation. Drill Bits. Carbide-Tipped Drill Bits for Masonry and Concrete, Hex Shank for Rotary Only Drilling.
    The hex shape reduces the chance of the shank slipping in the chuck. Pair these bits with hand-held power drills and hammer drills set to rotary-only mode. Because they use rotary action only, they require more pressure to grind up material than other bits.

    Tapping Screw Installation Drill Bits for Masonry and Concrete

    Create an undersized hole so concrete tapping screws fit tightly once they're threaded into place. These bits are slightly smaller than the matching screw size. They have a carbide tip that resists wear and heat to stay sharp.

    Rebar-Cutting Carbide-Tipped Drill Bits

    No need to move the hole when you encounter rebar in concrete—swap out your masonry bit for one of these cutters. They have a carbide tip that resists wear to stay sharp. Once you're through the rebar, resume drilling with the masonry bit.
