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.

Round-Shank Drill Reamers

Drill and finish holes in a single pass with these dual-purpose tools. The tapered tip gradually pierces your material to reduce friction, and the straight flutes make clean cuts without chipping or peeling the edge of the hole. Made from solid carbide, these drill reamers are strong and heat resistant. The flutes stay sharp even when cutting abrasive materials such as carbon fiber, fiberglass, and graphite. Use them in drill presses or other machines—carbide is brittle, and will break if used to drill by hand.
