    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.

    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.

    Straight flutes are used for general purpose cutting. Since chips are forced forward into the hole, they perform best in through-hole applications.

    Expansion Reamers

    Twist the set screw to expand the flutes and grind to their original diameter. These reamers enlarge and smooth holes.
    Not designed for producing holes larger than the listed diameter or for producing holes of various sizes. The adjustment set screw should never be loosened. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.
    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.

    Adjustable-Size Reamers

    Create and finish multiple hole sizes with one tool by moving the adjustable blades within the diameter range. These are often used for reaming bushings to a precise fit when the size needs to be determined during assembly. The blades can be reground and replaced. Adjustable reamers are not as rigid as standard reamers, so vibration can cause "chatter" that results in misalignment and poor finishes. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.
    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.
    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.
    Use steel reamers on plastic and metals such aluminum, stainless steel, and steel. They're not as durable high-speed steel.

    Adjustable-Size Hole-Alignment Reamers

    One tool straightens, enlarges, and deburrs multiple sizes of misaligned and overlapping holes. Also known as bridge, car, and aligning reamers, they have a tapered tip for easy entry into misaligned holes. To change the reamer size, move the adjustable blades within the diameter range. These blades can also be reground and replaced. Adjustable reamers are not as rigid as standard reamers, so vibration can cause "chatter" that results in misalignment and poor finishes. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.
    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.
    Square Shank with Built-In Pilot
    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. A built-in pilot maintains alignment in the hole.
    Use steel reamers on plastic and metals such aluminum, stainless steel, and steel. They're not as durable high-speed steel.

    Taper-Pipe Reamers

    Size and shape a hole to a tapered pipe size prior to tapping, ensuring a tight fit when joining threaded components. These reamers create a taper and leave a smooth finish. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.

    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.

    Reamers for Morse Taper-Socket Holes

    Turn straight holes into Morse taper socket holes that can hold cutting tools or adapters in machine spindles. These reamers are also good for sizing and smoothing existing Morse taper holes and removing nicks and burs from spindles. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.

    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.

    Adjustable-Size Reamer Sets

    Each reamer in these sets can create and finish multiple hole sizes by moving the adjustable blades within the diameter range. They are often used for reaming bushings to a precise fit when the size needs to be determined during assembly. The blades can be reground and replaced. Sets include a variety of reamer size ranges. Adjustable reamers are not as rigid as standard reamers, so vibration can cause "chatter" that results in misalignment and poor finishes. Note: Never rotate the reamer in the reverse direction of the cut. This will ruin its accuracy.
    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.
