R8 Collet

An R8 collet is a type of tool holder commonly used in milling machines and machining centers. It features a tapered design that allows for a secure grip on a variety of tools, such as end mills or drill bits. The R8 collet system is characterized by its easy-to-use design, where the collet is tightened and loosened using a drawbar mechanism. This makes changing tools quick and efficient.

R8 collets are typically made from high-strength materials to withstand the forces encountered during machining. They come in various sizes to accommodate different shank diameters, and their consistent accuracy ensures that tools are held securely, minimizing runout and improving machining precision. Overall, R8 collets are favored for their reliability and versatility in a range of machining applications.
