    Drill Bits

    Cut holes in a variety of metals, from the softest aluminum to the hardest steel.

    Our basic drill bit material is also the most versatile. These jobbers' bits have the balance of rigidity and length needed for most applications.
    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.
    Gold Oxide—Like black oxide, this finish adds wear resistance and reduces friction for improved chip flow. Because it’s less prone to flaking off, it offers better rust protection when bits aren't in use.
    Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.
    Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.
    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.

    Split

    Our shortest high-speed steel bits, these are the most rigid for drilling the straightest holes. They're also good for tight spaces where longer bits can't fit. Also known as screw-machine and stub-length bits.
