An oversized diameter allows for finishing to your exact requirements. Gray cast iron machines faster with less wear on cutting tools than most types of steel. It also absorbs vibration, so finished parts run quieter than those made of steel. It's often used for gears, pulleys, rollers, and bushings.

An oversized diameter allows for finishing to your exact requirements. Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion. These rods and discs are decarb-free for a uniform surface that will consistently accept heat treating.

If you don't see the size you're looking for, please specify a length under additional rod lengths.

An oversized diameter allows for finishing to your exact requirements. A2 tool steel is more wear resistant than O1 and it keeps a sharper cutting edge. This air-hardening material is widely used for punches, broaches, and dies. These rods and discs are decarb-free for a uniform surface that will consistently accept heat treating.

Made of naturally slippery acetal copolymer, these rods and discs are an economical alternative to Delrin® acetal resin. They offer similar wear resistance and are equally resistant to expanding when exposed to heat and moisture. They can be machined to close tolerances and are often used to make precision gears, bushing, bearings, and rollers.

Often machined into bearings, gears, cams, and valve seats, these wear-resistant nylon 6/6 rods and discs have a slippery surface that reduces friction.

Because these cast nylon 6 rods and discs are easier to machine than standard nylon 6/6, they’re often made into pulleys, screws, bushings, and bearings. They’re also better electrical insulators. They have a wear-resistant, slippery surface that reduces friction. This material is comparable to Nylatron and Nycast.

The addition of MDS gives these rods exceptional wear resistance along with a self-lubricating surface. They’re made of cast nylon 6, which is easier to machine than other MDS-filled nylon rods, plus they are better electrical insulators. Use them to fabricate gears, sprockets, wear strips, and other high-friction parts. This material is comparable to Nylatron and Nycast.

Offering a low-friction surface that prevents sticking and binding, these rods and discs are often machined into bushings and bearings. UHMW is impact and wear resistant to handle the scuffs, scrapes, and strikes that other plastics can’t.

Offering the same resistance to acids and alkalies as PVC, these CPVC rods stand up to higher temperatures. Use them to make parts for use in chemical-processing applications. CPVC is easy to thermoform and it’s an excellent electrical insulator.
