Round-Shank Reamers for Hole Alignment with Safety Collar
A collar on the shank prevents you from reaming past the cutting edge. These reamers are for use with hand-held electric and air tools. Also known as bridge reamers, car reamers, and aligning reamers, they ream, true, enlarge, align, and debur holes. All have tapered ends for easy entry into misaligned holes. They are not for reaming tapered holes.

Short-Length Round-Shank Reamers for Hole Alignment
Correct hole misalignment when working in confined spaces. About 2" shorter than standard hole-alignment reamers of similar thicknesses, these reamers give you extra room to move when there’s limited space between you and your workpiece. Use with hand-held electric and air tools. Not for reaming tapered holes.

Hex Nut-Shank Reamers for Hole Alignment with Safety Magnets
Spiral Flute
Helical Spiral Flute
Magnets on the hex nut hold the reamer in place in your tool and prevent it from accidentally falling when not in the square-drive impact wrench socket. Also known as bridge reamers, car reamers, and aligning reamers, they ream, true, enlarge, align, and debur holes. All have tapered ends for easy entry into misaligned holes. Do not use for reaming tapered holes.
Reamers with spiral flutes are a good choice for materials that are difficult to ream, such as high-carbon steel and cast iron.
Reamers with helical-spiral flutes create a fine finish and reduce the chance of breakage because they move chips forward, which prevents the chips from packing into the flutes.

Hex Nut-Shank Reamers for Hole Alignment
The hex nut on the end of the shank lets you use these reamers with square-drive impact wrench sockets. Also called bridge reamers, car reamers, and aligning reamers, they ream, true, enlarge, align, and debur holes. All have tapered ends for easy entry into misaligned holes. Do not use for reaming tapered holes.

Extra-Long Angle-Blade Adjustable-Size Reamers
A long, permanently mounted pilot steadied by a floating sleeve lets you align holes that are spaced far apart. Tighten or loosen the two nuts on the reamer to move the adjustable blades within the diameter range so you can ream multiple hole sizes with the same tool. These reamers are often used for reaming bushings to a precise fit when the size needs to be determined during assembly. Blades can be reground and replaced. To measure size, adjust blades to a known size (such as a bushing or ring), or measure across two opposite blades with a micrometer.
