Description

Product Overview

Swiss-type machine collets are precision workholding tools for the main spindle of sliding-headstock Swiss-type lathes. They hold raw bar stock concentrically during axial movement.

Collet accuracy directly affects the dimensional quality and surface finish of the finished part, as well as cutting-tool life. Each Swiss-type machine model requires its own matched collet.
