    Round Shank

    Drill inside walls and between floors to install electrical wiring without cutting extra access holes. The shaft on these bits flexes for a long reach in any direction. To install wire, first strip the end and attach it to the small hole at the tip of the bit. Then pull wire back through the drilled hole. Also known as bell hanger bits.

    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-Max

    Shank

    The slotted shank is compatible with SDS-Max-drive rotary hammers. These bits use simultaneous rotary and hammering action to penetrate material. Also known as percussion or impact bits.
