Collet not chuck sorryHi guys
I’m struggling bigstyle to identify this chuck and it took me buying a full set of er32 collets to figure it out the dimmensions are45mm in lengthView attachment 410641View attachment 410642View attachment 410643 and 29.5 in diameter photo attached
came to a similar conclusion myselfPossibly an OZ collet, but you would need to find drawings/dimensions to confirm/deny.
Edit:
On a hunch that the 20-20 engraved on it might not be a vision score from Specsavers, this appeared:
Collet 4541E (OZ20B) DIN ISO 10897 B, CL2
High quality collets OZ DIN 6388, made of spring steel, hardened and precision ground, type 4541E (OZ20), form B. These OZ collets according to DIN ISO 10897 B are slotted on both sides Twist drills can also be short-clamped on...www.fwt-gmbh.de
