This for one Collis End Mill Holder. It fits 1.25" diameter end mills. It has a 5MT taper. It is in excellent condition. Asking $60. Over $450 new. If you buy the holder, I have an end mill I can also sell you for an additional $30 that fits it. If interested, please call me. No texts as this is a land line.
