why does er 32 collets only go up to 20mm and not a little more I understand for safety it could not go too much more but could one take an er 32 20mm collet and widen it to say 22mm or such ?Alistair

I think the 20 mm is the limit and and still have a locking groove. 22mm is going into the groove or seriously weakening it.

Other than the groove, I think you will run into trouble on the small end. I don't have the dimensions right here; but I am thinking you will have to shorten the collet and the tool will bear on the small end of the toolholder.

Alistair,

There's no technical reason for it whatsoever - it's all an evil capitalist plot to make you go out and buy an ER40 collet and holder...
