This 6 inch 3-Jaw self-centering lathe chuck includes a chuck key, inside and outside jaws, and mounting bolts.

This chuck has a 1.57" (40 mm) through hole. The chuck can hold work up to 5.70" (145 mm) in diameter.

This is a plain back chuck and requires a backplate adapter to mount it.

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