    Fast-Cutting Smooth-Finish Drill Bits for Wood

    Not only do these bits bore holes faster than standard smooth-finish bits, they create less friction and heat buildup to last longer. The spurred teeth have a long life, but they're less effective at guiding the bit so cuts on angled and overlapping holes tend to be rougher. Also known as multispur bits.
    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.

    Smooth-Finish Drill Bits for Wood

    Image of Product. Front orientation. Drill Bits. Smooth-Finish Drill Bits for Wood, Round Shank.

    Round Shank

    Multiple teeth cut away large amounts of material to bore clean, flat-bottom holes in wood. The center guide point keeps the bit stable and centered for drilling straight, angled, and overlapping holes, like those used create joints. Also known as Forstner bits.

    Carbide-Tipped Steel

    Carbide tipped to stay sharp longer than tool steel bits, these are better on tough and abrasive materials, such as plywood and hardwoods. They have multiple teeth that cut away large amounts of material to bore clean, flat-bottom holes in wood. The center guide point keeps the bit stable and centered for drilling straight, angled, and overlapping holes, like those used create joints. Also known as Forstner bits.
