    Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.
    Short Length—The most rigid bits for drilling the straightest holes.
    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.

    Tight-Clearance Right-Angle Drill Head Adapters

    Image of Product. Front orientation. Contains Annotated. Drill Head Adapters. Tight-Clearance Right-Angle Drill Head Adapters.
    These right-angle adapters attach to a hand-held drill to reach fasteners in confined spaces with as little as 2" of clearance. Threaded shanks pull drill bits into the workpiece, reducing the push force needed in awkward positions. The 1/4" round shaft fits standard hand-held drill chucks.

    Thread these bits directly onto your driving tool for an extra-stable connection that minimizes wobbling. Phillips bits align easily with fasteners and deliver more torque than slotted bits.
    Steel—Best for dry environments, since moisture will cause these bits to rust.

    Straight Flute

    These reamers fit power drills that have a 1/4"-28 threaded spindle or adapter. Using a powered hand tool can affect alignment, so these have a built-in pilot that guides the reamer into the hole and keeps it straight.
    Straight Flute—The most common flute style, these reamers are suitable for a wide range of applications, but not recommended for holes with a keyway or other breaks in the surface.
    High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.
