Dead Centers
Dead centers are one solid piece. Use them in the headstock when machining between centers or in the tailstock to support the end of a workpiece when friction is not a concern.
Carbide-tipped hardened steel dead centers have better wear resistance than hardened steel dead centers.

Grippers
Maintain a secure hold on uneven or irregularly shaped parts by clamping against these serrated grippers.
Fine serrations penetrate the workpiece for aggressive holding.
Extra-fine serrations are closer together for less penetration and a lighter hold on the workpiece.
