    Split

    The toughness and wear resistance of cobalt steel in a length that's rigid enough for most applications. Cobalt lasts at least twice as long as high-speed steel. It can also run up to 25% faster at higher temperatures without damaging the bit on hard materials such as nickel.
    Uncoated—Polished to eject chips, these are also known as bright finish bits.
    Morse Taper Shank—Insert directly into the tapered spindle on machines such as drill presses and lathes.
    Split Point—Starts cutting on contact so you don’t need a pilot hole. The point also keeps the bit centered for straight and accurate holes, even with a portable drill.

    Carbide-Insert Drill Bits

    When you need to drill dozens or even hundreds of holes, use a bit with replaceable carbide inserts. Once the cutting edges wear down, just change the inserts instead of sharpening or throwing the bit away. The holes in the bit channel coolant through the tool for more efficient chip evacuation. Each drill bit requires two inserts—one on the inner cutting edge and one on the outer cutting edge. Replacement inserts are sold separately.

    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.
    Standard Point—The most common point type handles most jobs. However, for more aggressive cutting that generates a lot of heat, consider a multipoint or serrated bit.
