Drill Rod Tool Steels 860326 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 860326 is an O1 oil-hardening tool steel flat bar cut to 3/16 inches thick, 1-1/2 inches wide, and 18 inches long. Conforming to AISI Type O1 material specification, this flat stock is a versatile pre-cut blank used by machinists, tool-and-die makers, and fabricators who need a reliable, heat-treatable steel in a ready-to-machine form. O1 tool steel offers good dimensional stability during oil-quench hardening, making it a standard choice for punches, dies, gauges, blades, and custom tooling applications. At 1.43 pounds per piece, it is sized for benchtop or machine shop handling without additional shearing.

This flat stock is suited for job shops, maintenance shops, and tool rooms requiring short-run or single-piece blanks for custom tooling, fixtures, or replacement cutting components. The 18-inch length provides enough material for most standard tooling blanks while keeping stock manageable. It is sold in single-piece quantities, making it practical for one-off projects or low-volume production runs where purchasing full bar stock is not cost-effective.

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat blank suitable for machining into punches, dies, blades, gauges, and general tooling components requiring oil-quench hardening.

Installation Notes

Machining and heat treating of O1 tool steel should be performed by qualified machinists or tool-and-die professionals familiar with oil-hardening procedures. Allow the steel to reach a uniform austenitizing temperature before quenching in oil, and follow established tempering cycles to relieve quench stresses. Use appropriate cutting fluids during milling, grinding, or turning operations to control heat buildup. Wear appropriate PPE when handling during heat-treat operations.
