JT33 to ER-32 collet chuck, milling chuck holder.
This collet chuck is hardened and precision ground and has a T.I.R. is <= 0.0002" (0.005 mm). The chuck will hold all ER-32 collets.
ER-32 collets have a range of 1/16" to 13/16" (1.0 mm to 21.0 mm).
*Collet must be assembled into a collet chuck nut before inserting into the collet chuck.
With all ER collet chucks, the collet must be snapped into the nut before placing it into the chuck. There is an eccentric ring inside the nut that engages the groove in the collet. That is what makes them self-ejecting. Tilt the collet again to remove it from the nut.
