Does anyone know where I could find a 1" collet that fits the PSI collet/chuck system? The largest collet that comes with the kit is only 3/4". Thanks.
I'm going through the exercise right now of deciding on an ER32 or ER40 collet chuck so have spent the last couple days looking at a lot of information. A couple machinist sites pointed to looking at www.rego-fix.com as a good source of information on the ER system. According to their catalog, they make a 13/16" collet for ER32 but that's the largest size. To go to a 1" collet you would need an ER40 chuck.
The main application that I've seen for these so far is drilling blanks. What else are you (or others) doing with them that the through capacity (as is allowed with the PSI or Bealle) is needed? From the specs that I can find, the ER32 collets are 1.5" deep and the ER40 collets are 1.8" deep so you could insert at least that much of a blank into an MT mounted collet chuck.
I'd still like to hear from someone the advantage of using a chuck like the PSI or Bealle that threads onto the spindle versus a morris taper mounted chuck. I can see that it would me more accurate/stable to have it screwed onto the spindle but I'm having trouble seeing that the ability to put a blank all the way through into the headstock is a big advantage.
Hey Eric -- If what you foresee in your future turning does not need the ability to have more depth, go ahead and get what ever -
