About 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.
