I have 19 of these collets chucks for sale. Some are marked "ATC 2-25-20" and others are unmarked but otherwise identical. They are very low profile er20 chucks, very nicely made. I believe the part number ID's them as made by Precise. All are balanced for high speed (both chuck and nut), and they came out of a mold shop that had several machines with 30,000 and 40,000rpm spindles.

I'd like $15/holder, or $250 for all of them. They can likely all fit in a large flat rate box for shipping.

Thanks,

Lee
