Hardinge R8 collets are the result of over 100 years of experience in serving the needs of the machining industry. The Hardinge R8 collet is manufactured to exacting standards from special alloy steel. All Hardinge R8 collets are a solid one piece design, hardened and spring tempered to assure accuracy and durability.

Precision R8 Collets for manual and CNC milling machines are carburized and case hardened for maximum wearability and strength. They are harder than any other R8 collet on the market. A custom process is used to eliminate the use of bushings for the internal draw threads.
