I bought a vintage, or was listed as vintage, Keller 2RG die grinder and the collet is worn out on it and doesn't hold any bits. I've tried looking around and the closet looking ones I could find are for mills. It's a 1/4" collet and I would like to be able to use it since it still works and seems to have a lot of life left in it, I also tried making the slot in the collet bigger so it would close up more but it only helped a little before the nut bottomed out. If anyone happens to know where I can get a replacement collet it would be greatly appreciated.
