As the title says, I have a collet chuck that came with the mill... but I have no idea what sort. Its on an MT3 taper. The chuck can handle anything up to 0.7" (17.7mm) through the nut and the internal opening for the collet in the main body is .88" (22.4mm) at the top. The nut is about a 1.25" (32mm) thread. The outer dimensions are 1.89" (48mm) dia and from the top of the nut to the gauge line is 2.6" (66mm). The nut has a steep taper, the chuck body a very shallow one.

Ideas?

If you can post a picture of the collet, I'm sure it will be identified very quickly

HI irving 2008

Try Clarkson autolock the female part is clarkson but the nut does not look to be Clarkson but they may have made different types of nuts

Try this one Clarkson Posilock Collet Chucks the Auto-Lock has a different Collet

Thanks, it is indeed a Posilock, knowing that helped me find out the other info I needed... including making the decision to go for MT3 collets rather than buy collets for this...

Anyone want a Posilock chuck?
