About This Product
Got a CNC mill or router?

This ER11 spring collet set is exactly the kind of handy addition you need.

You get two collets – one 1/8 inch (3.

175mm) and one 1/4 inch (6.

35mm) – both with an 18mm overall length.

Made from quality spring steel, they're tough, durable, and give you a nice wide clamping range with solid holding power.

They work great for boring, milling, drilling, tapping, engraving, and pretty much any CNC operation you throw at 'em.

The build is precise, so your tools stay locked in place without wobble or slip.
Easy to install too – just pop 'em into your ER11A or ER11N holder, tighten the pressure cap, and you're good to go.
Reliable, affordable, and ready to work.

If you run a machine shop or a garage workshop, these little guys will earn their keep real fast.
