    Reamers

    Finish holes to precise inch, metric, wire gauge, or letter sizes with these reamers.
    Adjustable Size, Square Shank
    Finish multiple hole sizes with one reamer by moving the adjustable blades within the diameter range. Convenient for maintenance work, these have a large diameter range and don't require powered tools. They're often used to make precise size adjustments during installation of bearings and bushings.
    Move the blades by tightening and loosening the two nuts on the reamer. To measure size, adjust blades to a known size (such as a bushing or ring), or measure across two opposite blades with a micrometer. When the blades become worn, they can be reground or replaced.
    Turn these reamers by hand with an adjustable wrench or straight-handle tap wrench (sold separately).
    Extension pilots (not included) can be used in place of the end adjustment nut to align holes that are spaced far apart.
    Straight Blade—Use these reamers in straight holes that don't have a keyway or other breaks in the surface.
    Angled Blade—These reamers are better than those with straight blades for finishing holes with breaks in the surface, such as a keyway.
    High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.
    Tool Steel—Typically more economical but less durable than high-speed steel, these are for general purpose reaming.

    Reamers for Hole Alignment

    Enlarge holes to correct misalignment and overlap. Misaligned holes often have a narrow entry, so the tapered shape is easier to insert and makes more contact to remove the overlapping material. These are also known as bridge and car reamers.

    Angled Blade

    One tool both finishes multiple diameters and enlarges holes to correct misalignment and overlap. Also known as bridge and car reamers, they have a tapered shape that fits into the narrow entry of misaligned holes and makes more contact to remove the overlapping material. Change the reamer size by moving the adjustable blades within the diameter range.
    Move the blades by tightening and loosening the two nuts on the reamer. To measure size, adjust blades to a known size (such as a bushing or ring), or measure across two opposite blades with a micrometer. When the blades become worn, they can be reground or replaced.
    Turn these reamers by hand with an adjustable wrench or straight-handle tap wrench (sold separately).
    Angled Blade—These reamers are better than those with straight blades for finishing holes with breaks in the surface, such as a keyway.
    Tool Steel—Typically more economical but less durable than high-speed steel, these are for general purpose reaming.
    Long Reach—Align holes spaced far apart with reamers that have a long, built-in pilot. A floating sleeve guides and steadies the pilot through holes.

    Work on a wide range of hole diameters by keeping a set of adjustable reamers on hand. Each reamer can finish multiple hole sizes by moving the adjustable blades within the diameter range. Convenient for maintenance work, these don't require powered tools. They're often used to make precise size adjustments during installation of bearings and bushings.
    Move the blades by tightening and loosening the two nuts on the reamer. To measure size, adjust blades to a known size (such as a bushing or ring), or measure across two opposite blades with a micrometer. When the blades become worn, they can be reground or replaced.
    Turn these reamers by hand with an adjustable wrench or straight-handle tap wrench (sold separately).
    Straight Blade—Use these reamers in straight holes that don't have a keyway or other breaks in the surface.
    Angled Blade—These reamers are better than those with straight blades for finishing holes with breaks in the surface, such as a keyway.
    High-Speed Steel—Durable and wear resistant, these are good for general purpose reaming in most materials.
    Tool Steel—Typically more economical but less durable than high-speed steel, these are for general purpose reaming.

    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.

    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.
    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.
