An R8 collet is a specialized clamping device used in machining and milling. It is designed to hold workpieces securely in place, allowing for precise cutting, shaping, and drilling operations. The “R8” designation refers to the taper size of the collet, which is commonly found on milling machines.

The R8 collet is manufactured to exacting standards from special alloy steel. All R8 collets have a solid one-piece design, hardened and spring-tempered to ensure 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.
