Drill Rod Tool Steels 57960 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57960 is an O1 oil-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require a reliable, machinable steel that hardens predictably in an oil quench. This flat bar measures 0.5 inches thick, 6 inches wide, and 36 inches long, and weighs approximately 30.93 pounds. AISI Type O1 tool steel offers good wear resistance and dimensional stability through the hardening process, making it a standard choice for punches, dies, gauges, and precision tooling components where tight tolerances matter from the start.

This flat stock is suited for machine shops, tool and die operations, and fabrication environments handling general-purpose tooling work. The 0.5 inch by 6 inch cross-section and 36 inch length make it practical for cutting down into multiple blanks for dies, stripper plates, and flat tooling. The stock arrives in the annealed condition, ready for machining before heat treatment. Typical users include tool and die makers and precision machinists in both job shop and production settings.

Compatibility

Designed as a general-purpose O1 oil-hardening tool steel flat stock suitable for tooling, die making, and precision machining applications requiring AISI Type O1 material specification.

Installation Notes

Machining and heat treatment of tool steel flat stock should be performed by qualified machinists or tool and die makers familiar with O1 oil-hardening procedures. Always anneal or stress-relieve the workpiece if heavy stock removal is performed prior to hardening. Appropriate eye protection, secure workholding, and proper cutting speeds for tool steel are required during machining operations. Follow the steel supplier or AISI guidelines for quench media and temperature when hardening.
