Our Chucking Reamer selection is one of the deepest in the industry, with straight flute and spiral flute options available in HSS, Cobalt, and Carbide, and in right-hand or left-hand spiral configurations. HSS Intermediate Sizes fill in the gaps between standard fractional sizes for closer tolerance matching.

Spiral flute chucking reamers help clear chips more efficiently in blind holes and through-holes alike, while straight flute versions are often preferred for interrupted cuts like keyways. Cobalt chucking reamers offer better heat resistance for stainless and tool steel work compared to standard HSS. With over 5,000 chucking reamers in stock, USA manufactured and ready to ship same day, we're built to match your exact tolerance and material needs.
