Sherline PN 1076C 4-Jaw Self Centering Chuck Nickel-Teflon coated
This chuck will hold parts from 3/32″ in
diameter up to 1-1/2″ with jaws in the normal position and up to 2-3/4″
with the jaws reversed.
This chuck is identical to P/N 1076 except for an electroless Nickel-Teflon coating that has been applied to help prevent wear and corrosion. This special coating has been applied to all external and internal surfaces of the chuck (except for chuck jaws), significantly improving the life of the chuck. This chuck also opens and closes more smoothly due to the lubrication properties of Nickel-Teflon.

This chuck combines the ease-of-use
advantages of the 3-jaw chuck with some of the advantages of a 4-jaw
chuck. It will automatically center square or round stock. (The stock
must be accurately shaped for all four jaws to grip.) It 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. If perfect centering
accuracy is required, see the section on 4-jaw independent jaw chucks.
