Grade O-1 Drill Rod Tool Steel is one of the most widely selected grades of drill rod. It is made from grade O-1, an oil-hardening, non-deforming general tool steel. Tools and dies made from grade O-1 will have good wearing qualities since the tungsten and higher chromium content of O-1 offers improved wear resistance. O-1 is ideal for manufacturing bushings, dies, knock-out pins, shims, machined parts and slitting cutters, among many other uses.
