Hard Jaws provide strong, durable clamping for heavy-duty machining and high-strength applications.

Hard Jaws share certain characteristics of soft jaws. They are made of case-hardened steel – EN353 and hardened up to 50-55 HRC. They are usually used for first-operation roughing, where gripping is a more important criterion than concentricity. The ground gripping surface of the jaw provides a secure true grip.

Key Features & Benefits
