I've seen these straight shank ER collet chucks in the Enco flyers and was wondering a few things about them. Is this the kind of thing that you could chuck up in the four jaw to give you the advantages of collets while still being able to turn larger stock if you need it? It looks to me from the pictures that the chuck is tightened using the nut at the front end of the chuck (the end with the collet) rather than a draw bar. Is that correct? Is there a through hole in the shank? If so, is it the same size regardless of the shank diameter? I'm looking at an ER 32 and they are available in 1, 1.250, and 1.500" diameter shanks. I mainly want it to make machining thin walled tubing a bit easier and faster. Anyway, I'd like to know a bit more about them before I spend some coin on them.
Thanks,
