    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.

    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.

    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.

    Chip-Clearing Carbide-Tipped Drill Bit Sets for Masonry and Concrete

    Prevent frequent stops to clear bits and reduce heat buildup that can damage them. The tight spiral flutes lift dust and debris out of the hole more quickly than standard masonry bits. These bits are especially effective for brittle material that creates a lot of debris, such as block and brick. The carbide tip resists wear to stay sharp.

    Chuck

    Keyed Chuck

    Turn your rotary hammer into a drill. These chucks mount directly into the SDS chuck to hold round- and hex-shank bits.
    Keyless Chuck—Keyless chucks let you swap bits in and out with a quick twist of the sleeve.
    Keyed Chuck—Keyed chucks grip bits tighter than keyless chucks do. Use the included key to tighten or loosen the jaws.
    Hammer and Rotary—Hammer and rotary chucks can be used in all modes, so you can fasten, hammer drill, and chisel with the same tool.
    Rotary Only—Rotary only chucks require you to switch your tool into rotary-only mode before using them.
