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.

Quick-Change Hole Saw Arbors with Pilot Drill Bit
A special collar on these arbors helps you quickly swap out tools. These arbors connect your hole saw to a drill or drill press, and they include a pilot drill bit that centers your cut and guides the saw. When the bit gets dull, you can pull it out without any special tools—just pull back on the quick-release collar. These arbors fit all brands of threaded and unthreaded hole saws.
Hole saw quick change arbors release your saw without unthreading it—just pull back the collar or push a button.
Carbide-tipped steel pilot drill bits last up to twice as long as high-speed steel pilot drill bits.

Hex-Head Gripper Screws
Make quick height adjustments by turning the threaded stud. Screw these grippers into place from above and clamp against them. The serrations penetrate the workpiece surface to hold uneven or irregularly shaped parts.
Extra-fine serrations are closer together than fine serrations for less penetration and a lighter hold on the workpiece. Fine serrations penetrate the workpiece for aggressive holding.
Fine threads are closely spaced for more precise adjustments than coarse threads. They also resist loosening from vibration better than coarse threads.
