DA (Double Angle) Collets

 

[Just for fun]

It's a DA series collet

 

[mattthemuppet2]

yup, definitely DA, maybe 150s. Used in drill/ endmill extensions

Different IDs, I can't fathom what I would use them for, I thought they would fit my die grinder, they do not

I have a dozen or so Erickson extension holders at home that the collets look similar . I'll check them out next week .

I have a set of Erickson 200's with a #2 Morse taper holder for a lathe. Sure look just like those.
Haven't used them in years since I went to ER's.
