Hi everyone.

I think your response will be NO, but I have to try it.

I own a minimill. It has morse cone 2 and I use a ER25 collet holder. Can I change the collets without removing the collet holder? I grab the collect with a wrench, and loose the nut whith the especific wrench for that.

Is very convenient, but I don´t know if it is a proper way.

Thank you

best regards

I believe that's one of the benefits of using the ER collet system, so I'd say yes....

That is a very big benefit to using ER collets. My mill/drill has an R8 spindle. I have an ER32 collet chuck with an R8 shaft for the spindle. I have never removed it since I installed it. To change collets you need a collet wrench for the nut and a large wrench that fits the chuck body. I use a large adjustable wrench. Really quick and easy to change collets.
