About Reamers

Inch Size Hand Reamers for Taper-Pin Holes
Hand turn these reamers with an adjustable wrench, straight-handle tap wrench, or pin vise (sold separately) to ream existing holes for use with standard taper pins.
Straight-flute reamers are for general purpose cutting.
Spiral-flute reamers 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 create a smoother finish than straight flutes and work well in keyways and other applications with an interrupted cut.
For pin size numbers 7/0 to 4/0, use an adjustable wrench or pin vise. For pin size numbers 3/0 to 14, use a straight-handle tap wrench.

Inch Size Round-Shank Reamers for Taper-Pin Holes
Use these reamers in drill presses, turret lathes, screw machines, and other machine tools to accurately ream existing holes for standard taper pins. The helical flutes have a left-hand spiral that pushes chips downward to reduce the risk of breakage and create a smooth finish.
