About This Product

This WEXWE ER20 spring collet is built for precision work.

It's a 1/2-inch collet with accuracy within 0.

008mm – that's seriously tight tolerance for CNC milling, engraving, and lathe work.
Handles speeds up to 5000 RPM without issue.

It's made from 65Mn spring steel with a hardness of 55HRC, so it's tough and holds its clamping force over time.

The double-angle design gives you powerful, parallel gripping – no wobble or slipping on your tooling.

And there's a built-in self-release feature that makes changing tools easier.

Installation is tool-free – just pop it in and out with your hands.

Works great for boring, milling, drilling, tapping, grinding, and engraving applications.

If you need reliable tool holding for your CNC router or spindle machine, this collet is a solid pick.
