    Shank Type

    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.

    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.

    Round Shank for Hammer and Rotary Drilling
    Image of Product. Front orientation. Drill Bits. Tapping Screw Installation Drill Bits for Masonry and Concrete, Round Shank for Hammer and Rotary Drilling.
    Use these bits in rotary hammers that have a drill chuck. Simultaneous rotary and hammering action drills faster and penetrates material with less pressure than rotary-only bits. Also known as percussion or impact bits.

    Quick-Change Hex Tapping Screw Installation Drill Bits for Masonry and Concrete

    Save time when drilling holes for tapping screws. These bits snap into impact drivers or other power tools that accept a 1/4" hex shank. They cut holes that are slightly smaller than the matching screw size for tight fit for once screws are threaded in. The carbide tip resists wear and heat to stay sharp.
    Quick-Change Hex Shank for Rotary Only Drilling
    Image of Product. Front orientation. Drill Bits. Quick-Change Hex Tapping Screw Installation Drill Bits for Masonry and Concrete, Quick-Change Hex Shank for Rotary Only Drilling.
    Because these bits use rotary instead of hammering action, they require more pressure to grind up material.
    Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.
