    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.
    3D CAD models availableFor technical drawings and 3-D models, click on a part number.
    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.
    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.

    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.

    Hole-Alignment Reamers

    Straighten, enlarge, and deburr misaligned and overlapping holes. Also known as bridge, car, and aligning reamers, they have a tapered tip for easy entry into misaligned holes. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.
    Hex Shank with Safety Magnets
    The hex nut on the end of the shank lets you use these reamers with square-drive impact wrench sockets. Magnets on the hex nut hold the reamer in your tool so it won't accidentally fall out.
    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.
