This is an interesting discussion. I bought an ER40 set for my mill and recently bought an ER40 - MT4 setup for my lathe. Now I am able to use the same collets on both my mill and lathe. I didn't do much research before going with ER40. What are the advantages of going with ER25 or ER32? Is it just that they are smaller in size?
My original set had an R8 mount holder which had fairly poor run-out so I ended up replacing it with a holder from Maritool. Luckily all of the collets were fine.
