Tight-Tolerance Oil-Hardening O1 Tool Steel Rods
 |
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.

Undersized Hardened Multipurpose M2 High-Speed Tool Steel Rods
|
These rods, also known as drill blanks, have an undersized diameter for machining your own drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.

Tight-Tolerance 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.
