100% Brand New ER25 Collet Chuck — Carbon Steel, 25mm Bottom Diameter, for Boring & Drilling

Designed for precision CNC milling, engraving and lathe work, this ER25 spring collet is 100% brand new and made from carbon steel. It has a 25mm bottom diameter and a wide clamping range of 2-16mm to fit many tool shank sizes. A specially shaped chute increases rigidity and helps hold tools firmly to reduce slippage during boring and drilling. Manufactured for balanced performance, the collet offers a runout tolerance of 0.015mm and a T.I.R. of 0.0003" to ensure accurate, repeatable machining.
