Cleveland C25663 Chucking Reamer

Practical limits of straight HSS reamers

Straight-flute high-speed steel reamers suit through-holes and light interrupted cuts where coolant can reach the flutes. They are less suited to deep blind holes or high-volume production where chip evacuation and tool life demand spiral flutes or coated carbide alternatives.
