Drill Rod Tool Steels 58282 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 58282 is an O1 oil-hardening tool steel flat bar cut to 0.625 inches thick, 2.5 inches wide, and 36 inches long. O1 is a general-purpose oil-hardening tool steel conforming to AISI Type O1 specification, widely used in toolmaking, die making, and precision machining applications. The stock ships in an annealed, machinable condition ready for rough machining, heat treat, and finish grinding. Tolerances are held tight: thickness at plus or minus 0.001 inches, width at plus 0.005 minus 0.000 inches, and length at plus 0.5 inches, making this suitable for precision tool room work. Weighing approximately 16.12 pounds per piece, this is a full 36-inch bar.

This flat stock is suited for tool and die shops, machine shops, and maintenance departments fabricating or repairing punches, dies, gauges, jigs, fixtures, and cutting tools. The 0.625-inch thickness and 2.5-inch width make it a practical starting size for a range of toolroom blanks. Machinists and toolmakers working in job shops or production environments will find this bar appropriate for medium-duty tooling applications that require oil-quench hardening followed by tempering to final hardness.

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat bar suitable for toolroom, die-making, and precision machining applications where oil-quench heat treatment will be performed.

Installation Notes

Machining and hardening of O1 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel heat treatment procedures. Follow the material supplier and furnace manufacturer guidelines for austenitizing temperature, oil quench, and tempering cycles specific to O1 grade. Always wear appropriate PPE when handling oil quench operations. Cutting and grinding operations should comply with applicable shop safety standards and OSHA general industry requirements.
