Oversized High-Speed Steel Round-Shank Reamers
The reamer diameter accounts for the 0.001" oversized diameter rating, so these reamers create a looser fit than standard reamer sizes. 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. Reamers with a left-hand spiral push chips downward as they cut, making them good for through holes.

Oversized Cobalt Steel Round-Shank Reamers
These reamers create a looser fit than reamers with standard diameters. They are cobalt steel for good performance on hard-to-machine materials. The reamer diameter accounts for the 0.001” oversized diameter rating. The shank diameter is slightly smaller than the reamer diameter.

Undersized/Oversized High-Speed Steel Reamer Sets
These reamers allow for a slightly tighter or looser fit than standard reamer diameters.
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.
