Arbor-Mount Reamers
Smooth and expand hole diameters that are 1 3/4" and larger with these reamers. Use a compatible arbor (sold separately) to mount them to your drill press or other machine. Also known as shell reamers.

Expansion Round-Shank Reamers
When the reamer wears down, twist the set screw to expand the diameter, and then grind the reamer to its original size. These reamers are carbide-tipped tool steel for excellent abrasion and heat resistance when cutting hard and abrasive materials. The shank diameter is slightly smaller than the reamer diameter.
These reamers are not designed for producing holes larger than the listed diameter or for producing holes of various sizes. The adjustment screw should never be loosened.

Hex Nut-Shank Reamers for Hole Alignment with Safety Magnets
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.
