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.
