5 inch, 3-Jaw self-centering lathe chuck.

Includes chuck key, inside and outside jaws, and mounting bolts.

The chuck can hold work up to 110 mm (4.33") in diameter.

The radial runout of a test bar held in this chuck, when the chuck is mounted true, is 0.003" maximum.

Chris Chris' Tips
Some people want a chuck that can hold larger diameters. 4" chucks work well on the mini lathe, but it is possible to use a 5" chuck on the mini lathe.

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

Here are instructions for centering work in a 4-jaw chuck. It's easy if you follow this procedure.

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