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.

Tight-Tolerance Multipurpose Oil-Hardening O1 Tool Steel Rods
- Yield Strength: 50,000 psi
- Hardness: Rockwell B90 (Medium)
- Heat Treatable: Yes
- Maximum Hardness After Heat Treatment: Rockwell C65
- Fabrication: Hot Rolled
- 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. It can also be surface hardened with heat treating for added wear resistance. These rods have been manufactured to meet ASTM A681 standards for performance and quality.
