Metric Size Carbide Round-Shank Reamers

For high accuracy, a long tool life, and excellent performance on hard and abrasive materials, solid carbide provides strength, hardness, and wear resistance. These reamers require rigid tool holding to prevent breakage and are not for use with hand-held tools. The shank diameter is slightly smaller than the reamer diameter.

Metric Size Hand Reamers

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.
