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.
