    Reamers

    Enlarge holes to exact inch, metric, wire gauge, or letter sizes. Reamers also smooth the walls of holes. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.

    Round Shank
    The most common shank type, it fits in the chuck of drill presses, turret lathes, and other machine and power tools. Also known as chucking reamers.
    Use high-speed steel reamers for general purpose reaming on a wide variety of materials.
    Right-hand spirals pull chips upward as they cut, so they’re often used in blind holes.

    Expansion Reamers

    Twist the set screw to expand the flutes and grind to their original diameter. These reamers enlarge and smooth holes.
    Not designed for producing holes larger than the listed diameter or for producing holes of various sizes. The adjustment set screw should never be loosened. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.

    Round Shank
    The most common shank type, it fits in the chuck of drill presses, turret lathes, and other machine and power tools. Also known as chucking reamers.
    Carbide-tipped steel reamers have superior abrasion resistance and retain a sharper, harder edge at higher temperatures than high-speed steel and cobalt steel reamers. They're often used on hard and abrasive materials such as cast iron, nonferrous alloys, plastic, and hardened steel.

    Reamers for Morse Taper-Socket Holes

    Turn straight holes into Morse taper socket holes that can hold cutting tools or adapters in machine spindles. These reamers are also good for sizing and smoothing existing Morse taper holes and removing nicks and burs from spindles. Note: Never rotate the reamer in the reverse direction of the cut.
