Product Information

Description

4 inch, 4-Jaw self-centering lathe chuck for square or octagonal work.

The through bore of this chuck is 20 mm (0.79").

This lathe chuck can hold work up to 80 mm (3.15") in diameter.

Chris's Tips

Mount this chuck on a mini lathe with one of our chuck adapters. Or purchase a chuck with an adapter already mounted.

Here is a chart that provides Lathe chuck capacities and mounting dimensions.

This is a fairly specialized chuck for turning square or octagonal stock. A 4-jaw independent chuck is a lot more commonly used.
