    Morse Taper Shank

    Standard

    Our basic drill bits are also the most versatile. Cut holes in a variety of metals, from the softest aluminum to the hardest steel.
    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.

    Reamers

    Finish holes to precise inch, metric, wire gauge, or letter sizes with these reamers.
    Adjustable Size, Square Shank
    Finish multiple hole sizes with one reamer by moving the adjustable blades within the diameter range. Convenient for maintenance work, these have a large diameter range and don't require powered tools. They're often used to make precise size adjustments during installation of bearings and bushings.
    Move the blades by tightening and loosening the two nuts on the reamer. To measure size, adjust blades to a known size (such as a bushing or ring), or measure across two opposite blades with a micrometer. When the blades become worn, they can be reground or replaced.
    Turn these reamers by hand with an adjustable wrench or straight-handle tap wrench (sold separately).
    Extension pilots (not included) can be used in place of the end adjustment nut to align holes that are spaced far apart.
    Straight Blade—Use these reamers in straight holes that don't have a keyway or other breaks in the surface.
    Angled Blade—These reamers are better than those with straight blades for finishing holes with breaks in the surface, such as a keyway.
    High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.
    Tool Steel—Typically more economical but less durable than high-speed steel, these are for general purpose reaming.
