About Reamers

High-Speed Steel Round-Shank Reamers
The shank diameter is slightly smaller than the reamer diameter.
Straight-flute reamers are for general purpose cutting.
Spiral-flute reamers have a right-hand spiral and a right-hand cut. They pull chips upward as they cut, so they’re often used in blind holes. Spiral flutes create a smoother finish than straight flutes and work well in keyways and other applications with an interrupted cut.

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 fiberglass, carbon fiber, and graphite. Use them in drill presses or other machines—carbide is brittle, and will break if used to drill by hand.
