Wire Gauge Size High-Speed Steel Round-Shank Reamers


Wire gauge sizes 1 to 70 have a shank diameter that's slightly smaller than the reamer diameter. Wire gauge sizes 71 to 80 have a shank diameter that's equal to the reamer diameter.
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.
