4-Jaw Self-Centering Chuck

Sherline 3.125" 4-Jaw Self-centering Chuck
A four-jaw self-centering chuck is convenient for gripping round or square stock quickly. These chucks combine the ease-of-use advantages of the 3-jaw chuck with some of the advantages of a 4-jaw chuck. They will automatically center square or round stock. (The stock must be accurately shaped for all four jaws to grip.) They will also grip thin-wall tubing in four places rather than three, which spreads out the load and allows more grip without crushing the tubing.

Turning the knurled portion of the outer diameter of the chuck scrolls all four jaws in unison. Included with the chuck are two Tommy bars for tightening and loosening the chuck.

Centering accuracy on self-centering chucks is to within a few thousandths of an inch.
