    Reamers
    3D CAD models available

    Finish holes to precise inch, metric, wire gauge, or letter sizes with these reamers.
    Round Shank

    Straight Flute

    These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.
    Straight Flute—The most common flute style, these reamers are suitable for a wide range of applications, but not recommended for holes with a keyway or other breaks in the surface.
    High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.
    Carbide—For the highest level of accuracy when cutting hard materials, these are our hardest, strongest, and most wear-resistant reamers. They're used on materials such as iron, hardened steel, steel alloys, and plastic. Their hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the reamer from breaking.

    Reamers for Taper-Pin Holes
    3D CAD models available

    Shape holes to match the profile of taper pins. After drilling a hole that matches the size of the small end of the taper pin you want to install, use these reamers to taper and finish the hole.
    Round Shank

    Helical-Spiral Flute

    These reamers fit in the chuck of drill presses, turret lathes, and other machine and power tools, making them the most common shank type.
    Helical-Spiral Flute—Prevent clogging when removing excess material with helical-spiral flutes. They also leave a smoother finish than straight flutes.
    High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.
    Left-Hand Spiral—These reamers push chips downward as they cut, so they're often used in through holes.

    Square Shank
    Turn these reamers by hand with an adjustable wrench, straight-handle tap wrench, or pin vise (sold separately).
    Straight Flute—The most common flute style, these reamers are suitable for a wide range of applications, but not recommended for holes with a keyway or other breaks in the surface.
    Spiral Flute—Since these reamers clear chips better than straight flutes, they leave holes with a smoother finish. They're better for holes with breaks in the surface, such as a keyway, because they cut continuously across the breaks instead of moving in and out.

    Reamer Sets for Taper-Pin Holes
    3D CAD models available

    Used for shaping holes to match the profile of taper pins, these sets include a variety of reamer sizes. Drill a hole that matches the size of the small end of the taper pin you want to install, and then ream to taper and finish the hole.
