High-Speed Steel Round-Shank Reamers
The shank diameter is slightly smaller than the reamer diameter.
Straight-flute reamers are for general purpose cutting.

Carbide Round-Shank Reamers
Solid carbide provides exceptional wear resistance and high accuracy in addition to excellent abrasion and heat resistance when cutting hard and abrasive materials. These reamers require rigid tool holding to prevent breakage and are not for use with hand-held tools.

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.
