Tight-Tolerance Easy-to-Machine W1 Tool Steel Rods

Yield Strength: 50,000 psi
Hardness: Rockwell B95 (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Rockwell C65
Fabrication: Hot Rolled
Specifications Met: ASTM A686

Made with lower amounts of alloy elements than other tool steels, these W1 rods are highly machinable. Also called drill rods, they are precision ground and held to strict diameter and straightness tolerances. They’re ready to be turned on a lathe. These rods are decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them more machinable and leads to better results from heat treating or finishing. You can harden the surface with heat treating for added wear resistance or water harden for added strength. These rods are often used to make hammers, files, and reamers. All have been manufactured to meet ASTM A686 standards for quality and performance.

Hardness: Rockwell B90 (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment:
Inch sizes: Rockwell C65
Metric sizes: Rockwell C62
Specifications Met: ASTM A681

Ready for turning in a lathe, these rods are precision ground to a tight diameter tolerance. They’re also known as drill rod. Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion.

Spring-Back Multipurpose 304 Stainless Steel Wire

This wire bounces back after bending. Often used to construct springs and wire rope, 304 stainless steel is a good all-around choice for a wide range of applications.

PTFE-coated wire has a slippery surface, so it’s especially useful as a fish wire when navigating through confined spaces.

Ultra-Formable 260 Brass Rods

Yield Strength:
Inch sizes: Not Rated
Metric sizes: 9,000 psi
Hardness: Not Rated
Temper: H01 (1/4 Hard)
Heat Treatable: No
Specifications Met: ASTM B134

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware.

High-Strength Fracture- and Wear-Resistant Zirconia Ceramic Rods and Discs

Ideal for applications that must resist bending and wear as well as carry heavy loads, these rods and discs are often used for sleeve bearings and shafts instead of metal. Added yttria gives this material more strength and lowers the chances of cracking from impact compared to standard zirconia, alumina, and silicon nitride ceramic. If cracks do occur, they will not spread, extending the life and reliability of this material. It also means this zirconia blend resists wearing down from rubbing against another part or abrasion from chemical slurries.

Zirconia ceramic resists bending better than alumina and silicon nitride ceramic but does not withstand rapid temperature changes or high temperatures as well as other high-performance ceramics.
