Turn these reamers by hand with a straight-handle tap wrench (sold separately). The cutting end is slightly tapered to ease hole entry for the final sizing of drilled holes. Choose a straight-handle tap wrench that fits the diameter of your hand reamer. The flutes have a left-hand spiral and a right-hand cut. They push chips downward as they cut, so they’re often used in through holes. Spiral flutes also work well in keyways and other applications with an interrupted cut.

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 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.
