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.

Reamers for Taper-Pipe Holes
Use these reamers before tapping with taper-pipe taps. Turn by hand with a straight-handle tap wrench (sold separately). Flutes have a left-hand spiral and a right-hand cut and push chips downward, so they are commonly used in through holes.
