Rotary broaches manufactured with a proprietary hardening process can cut material as hard as 50 HRC with minimal tool wear, improving the production process for medical screws and other components.
“With a Rayco broach, you can broach hexes in 30-HRC parts with no significant wear on the cutter after 2,000 passes,” Mr. Rooney says.

Conventional heat-treated HSS creates this fine structure but at a lower hardness, therefore lacking the wear resistance compared to a Rayco heat-treated broach.”
