Collets

[cobra]

Looking at a new mill.
Why would I select ER32 collets vs ER25 or ER 16?
Thanks

I feel a heavier collet gives a better grip.
My little X2 has an ER32 holder and collets.

ER32 collets go up to 3/4" diameter, which might increase your work and toolholding abilities.

Why wouldn't you use R8 collets...they go up higher in size and a lot more common (lots of manufactures and cheaper). My mini mill uses R8 collets. A Grizz G0709.

Take a look at Tormach quick change tooling. Once you use it you'll love them. Less than 30 sec tool change and repeatable.

Are you looking for toolholding or workholding?

It would be helpful to know which mill you are considering and what the spindle taper is.

Thanks.
