Dead Centers
Insert these in your headstock to support your workpiece when machining between centers. Unlike live centers, dead centers don’t spin freely, so they give you a fixed point to stabilize your material. You can also use them in the tailstock to support the end of the workpiece when friction isn’t a concern. Made of through-hardened 52100 alloy steel—a material originally developed for bearings—these centers have exceptional hardness, strength, and wear resistance. That means you'll have to replace them less often than centers made of low-quality steel. You can also apply high-pressure grease on the point to reduce friction and wear.
Pipe and tubing centers hold large-diameter, hollow workpieces. Also known as bull-nose centers.
Carbide-tipped hardened steel dead centers have better wear resistance than hardened steel dead centers. They’re ideal for high-volume work and holding highly abrasive and hard materials.

Hex-Head Gripper Screws
The threaded stud lets you make quick height adjustments. Screw these grippers into place from above and clamp against them. The serrations penetrate the workpiece surface to hold uneven or irregularly shaped parts.

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.
