4-Jaw Chucks

  • 4" (100 mm) diameter
  • Includes chuck key and mounting bolts
  • Plain back mounting
  • Excellent for holding thin walled workpieces

Description

The jaws on this 4" 6-Jaw self-centering lathe chuck are hardened and ground.

Includes chuck key and mounting bolts.

Because the chuck is designed to hold tubing, outside jaws are not included.

This chuck has a 1.02" (26 mm) through hole. The chuck can hold work up to 3.15" (80 mm) in diameter.

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

Chris' Tips

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.
