    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.
    Carbide reamers are harder, stronger, and more wear resistant than carbide-tipped reamers for the highest accuracy. Use on hard and abrasive materials such as cast iron, nonferrous alloys, plastic, and hardened steel. Not for use with hand-held tools, they require rigid tool holding to prevent breakage.

    Straight flutes are used for general purpose cutting. Since chips are forced forward into the hole, they perform best in through-hole applications.

    Taper-Pipe Reamers

    Size and shape a hole to a tapered pipe size prior to tapping, ensuring a tight fit when joining threaded components. These reamers create a taper and leave a smooth finish. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.

    Square Shank
    These reamers have a square portion at the end of the shank so they can be turned by hand with an adjustable wrench or straight-handle tap wrench.
    Use high-speed steel reamers for general purpose reaming on a wide variety of materials.
    Left-hand spirals push chips downward as they cut, so they’re often used in through holes.
