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.

Oil-Hardening O1 Tool Steel Bars

Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion. These bars, also known as flat stock, are decarb-free for a uniform surface that will consistently accept heat treating. With an oversized thickness, length, and width, these bars can be finished to your exact requirements.

Precision Ground—Precision-ground bars have less stock to remove on the top, bottom, and sides for achieving a finished piece faster.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Made-to-Order O1 Tool Steel Rods

When an off-the-shelf size won't do, we'll get you the exact dimensions you need.

Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion. These rods are decarb-free for a uniform surface that will consistently accept heat treating. An oversized diameter allows for finishing to your exact requirements.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
