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 create a smoother finish than straight flutes and work well in keyways and other applications with an interrupted cut. Reamers with a right-hand spiral pull chips upward as they cut, so they’re often used in blind holes.
