    Drill Bits for Wood

    Image of Product. Front orientation. Drill Bits. Drill Bits for Wood.
    Make rough holes in wood for jobs such as running wire and pipe through framing studs and sheets. These bits have two sharp edges for faster cuts than fluted bits and won't cause the surface of the material to splinter. A centering point keeps them stable while drilling soft and hard woods such as pine, plywood, and oak. Also known as spade bits.

    Adjustable-Blade Drill Bits for Wood

    Image of Product. Front orientation. Drill Bits. Adjustable-Blade Drill Bits for Wood.
    Bore a variety of hole sizes with one bit—just slide the blade to the desired diameter and then tighten the screw. These have two sharp edges for faster cuts than fluted bits and won't cause the surface of the material to splinter. A centering point keeps them stable while drilling soft and hard woods such as pine, plywood, and oak. Like standard flat-blade bits, these drill rough holes but should be used in a drill press rather than a hand-held tool. Also known as spade bits.

    Clutch Bits

    Turn the butterfly-shaped screws commonly found on old vehicles and machinery. These bits withstand high torque without slipping and damaging the screw recess. Also known as Type G bits.
    Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included).
    Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.
    Steel—Best for dry environments, since moisture will cause these bits to rust.
