Tight-Tolerance Multipurpose Air-Hardening A2 Tool Steel Rods
Precision ground and held to a strict straightness tolerance, these rods are ready for turning in your lathe. Also known as drill rod, this A2 tool steel is more wear resistant than O1 and keeps a sharper cutting edge. It’s air-hardening, so it doesn’t require baths or quenching after heat treatment. This tool steel is often used for punches, blades, and hammers. These rods have been manufactured to ASTM A681 standards for performance and quality.
