    Reamers for Taper-Pin Holes

    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.

    Helix 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.
    Helix Flute—Prevent clogging when removing excess material with helix 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.

    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.
    Cobalt Steel—With better heat and wear resistance than high-speed steel, these reamers run up to 25% faster, last longer, and perform better on hard materials, such as cast iron, hardened steel, titanium, and stainless steel.
