Drill Rod Tool Steels 66796 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 66796 is an O1 oil-hardening tool steel flat stock bar measuring 3/32 inches thick, 1/2 inch wide, and 36 inches long. O1 is a general-purpose oil-hardening tool steel that offers good wear resistance, dimensional stability during heat treatment, and machinability in the annealed state. This flat stock is supplied in the annealed condition and is intended for fabrication of cutting tools, punches, dies, gauges, and jigs. Machinists, toolmakers, and metalworking shops are the primary users of this material. Tight dimensional tolerances make it suitable for precision tool and die applications where stock removal is controlled.

This flat stock is suited for use in tool rooms, machine shops, and production environments requiring a reliable general-purpose cold-work tool steel. Typical applications include blanking dies, forming tools, woodworking knives, taps, reamers, and precision gauges. The annealed condition allows conventional machining before oil-quench hardening to final hardness. It is appropriate for both prototype and short-run tooling work in light industrial and job-shop settings.

Key Features

• AISI Type O1 oil-hardening tool steel for consistent heat-treat response
• Annealed flat stock ready for machining prior to hardening
• Thickness tolerance of plus or minus 0.001 inches for tight dimensional control
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness: edge 0.003 inches, end 0.004 inches per inch of thickness

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat bar suitable for general tool and die fabrication applications where oil-quench hardenable cold-work steel stock is specified.

Installation Notes

Cutting, grinding, and machining should be performed in the annealed state before heat treatment. Oil hardening requires proper temperature control and quenching in an appropriate oil medium - follow established metallurgical procedures and applicable shop safety standards. Wear appropriate PPE when cutting or grinding tool steel. Consult material data sheets for recommended hardening temperatures and tempering cycles before processing.
