G'day all,
I'm just finishing off the list of stuff to buy for my PCNC 1100.
I'm kinda lost with all the different ER Collets.
The most common (shank) sizes that I use are: 1/4", 5/16", 3/8", 1/2", 5/8" and 3/4".
I've already figured out that the ER-20 will do up to 1/2". But it seems that the ER-32 will go down to
fairly small sizes as well.
I don't quite get why they overlap the ER-20 and ER-32 collet sizes.
If I'm starting from scratch, what's the smartest way to do this?
All help gratefully appreciated.
Michael
