This 4" 4-Jaw independent chuck includes an adapter to fit the mini lathe spindle. It includes a chuck key and reversible jaws.

The adapter mounts to the spindle with three studs so additional holes in the spindle are not required.

Chris' Tips

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.

This chuck is a bolt-on accessory with the adapter that is included. All 4" and larger chucks require an adapter to fit on the mini lathe, no matter how many holes there are in the spindle.

Don't forget to get a set of studs and nuts to mount it.

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.
