This collet chuck for ER-32 collets mounts on the lathe spindle in place of the lathe chuck or can be used as a fixture on a milling table.

The outside diameter of the collet chuck is 100 mm. It has a 72 mm registration diameter and mounts with three M8 bolts on a 84 mm bolt circle. The concentricity of this chuck is <0.0002" (0.005 mm).

Includes a basic collet wrench.

*Collet must be assembled into a collet chuck nut before inserting into the collet chuck.

Elizabeth A. ★★★★★

This collet chuck holds my smaller bits securely without any wobble, and the 4-inch diameter gives me plenty of clearance for my milling table setup. I've been using it with ER-32 collets down to 3/32", and the runout is practically nonexistent.

Emma X. ★★★★★

Swapped out my standard chuck for this ER-32 collet chuck, and the reduced runout on my smaller stock is immediately noticeable. It's nice to be able to use the same collets I already have for milling work on the lathe now.

Ellie O. ★★★★★

The 4" diameter gives me a solid grip on larger stock without any chatter, and the mounting was straightforward on my lathe spindle. I've been using it for a few weeks now, and the consistency in holding the ER-32 collets is exactly what I needed for repeatable work.
