Tool Steel Drill Rod O1 offers excellent dimensional stability during heat treatment, and otherwise decent attributes. O1 is an oil-hardening, general purpose tool steel. While not as strong or wear resistant as A-2 or D-2, it experiences significantly less distortion during the heat treating process. It is typically used in rolls, punches, shear knives, food processing knives, and gauges.

The O1 Drill Rod is available in two lengths: 36 inches and 72 inches, both precision ground for dimensional accuracy.

Yes, O1 tool steel offers excellent dimensional stability during heat treatment, making it ideal for applications like rolls, punches, shear knives, and food processing knives where minimal distortion is important.

Yes, a Material Test Report (MTR) is available for this O1 Drill Rod to verify its chemical and mechanical properties.

The O1 tool steel drill rod has a high machinability rating of 95, making it easier to machine compared to harder tool steels like A-2 or D-2.

The 0.413" diameter O1 Drill Rod weighs approximately 0.46 lb per inch. For example, the 36-inch length weighs about 1.37 lbs, and the 72-inch length weighs about 2.73 lbs, which influences shipping costs accordingly.
