    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.
    Carbide-Tipped Tool Steel—Since these reamers retain a sharper, harder edge at higher temperatures than high-speed steel and cobalt steel, they can be used on hard materials, such as iron, hardened steel, and steel alloys. They aren't as brittle as solid carbide reamers, so they can be used in less rigid setups, such as a hand-held drill.

    Straight Flute

    Unlike standard reamers, which are unusable once they become worn, these can be returned to their original size for finishing holes. After the reamer is worn down, tighten the set screw to expand the diameter, grind the reamer to its original size, and get back to work.
    These are not designed for producing holes larger than the listed diameter or for producing holes of various sizes. The set screw should not be loosened.
    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.
