    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.
    Cobalt steel reamers offer better heat and abrasion resistance than high-speed steel reamers to run up to 25% faster for a longer tool life. They're commonly used on hard-to-machine materials such as nickel alloys, stainless steel, and titanium.

    Reamers for Taper-Pin Holes

    Size, shape, and finish holes to precisely fit standard taper pins commonly used for positioning and alignment. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.
