    Jobbers' Length

    Image of Specification. Standard. Front orientation. Contains Border. Standard Point. For Metal.

    Standard

    Cut large holes with drill presses and portable drills that have a standard-size chuck. The shank on these bits has a smaller diameter than the cutting tip. High-speed steel is good for general purpose drilling in most metals. Also known as Silver and Deming bits.
    Jobbers' Length—These 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.

    Fast-Cutting Smooth-Finish Drill Bits for Wood

    Round Shank

    Standard Point

    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.
