ER32 "UM"?

<< < (2/4) > >>

sparky961:
I'm beginning to think that the set I have isn't actually ER32.  A quick search online wasn't able to clear up what I actually have though.

They look like ER32 but seem to be a lot longer (2.045" overall).  I was thinking maybe ER40 but the dimensions didn't match up to that either.  Any suggestions or sites that may help in the ID?

Unless I can figure out what they are and find an MT3 chuck they fit, my options are to a) shelve it until I have a machine with R8 spindle, or b) sell the collets and chuck as a set.

The nut from the new one is much smaller than the existing.  Kinda like trying to fit a square peg in a round hole. ;)  I should have been more careful about determining the actual collet size/type before purchasing a holder.

Swarfing:
It should be written or stamped around the rim what size and type it is. Sounds like a need for pic of all the components next to each other.

Yes, definitely time for some pictures.  I squinted at the old chuck for a while and wasn't able to locate any identifying marks.

Thanks for your clues!

They look like DIN collets to me not ER's
