Description

Product Overview

Special collets for small parts are precision workholding tools designed for clamping and machining very small components with diameters of a few millimetres or even below 1 mm. These collets provide close clamping tolerance, accurate concentricity and minimal runout.

Medical manufacturing, Swiss watchmaking, precision electronics and dental manufacturing are among the main users of these collets, where small-diameter parts must be held securely with close dimensional accuracy.
