Collet Chuck, ER-32, 4" Diameter

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.

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.

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.
