Drill Rod Tool Steels 00481 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 00481 is an O1 oil-hardening tool steel flat stock bar sized at 0.125 inches thick, 0.25 inches wide, and 36 inches long. Conforming to AISI Type O1 material specification, this flat stock is used by machinists, tool and die makers, and metal fabricators who require a precision-ground steel bar ready for hardening. The tight thickness tolerance of plus or minus 0.001 inches makes it suitable for applications where dimensional accuracy before heat treatment is critical. Weighing approximately 0.33 pounds per piece, it is easy to handle for bench work and small tooling projects.

O1 oil-hardening tool steel flat stock is a standard choice in tool rooms, machine shops, and fabrication facilities for producing punches, dies, blades, gauges, and fixtures. The 36-inch length provides sufficient stock for cutting multiple blanks from a single piece. This grade is well suited for applications requiring good machinability in the annealed state followed by oil-quench hardening to achieve high surface hardness and wear resistance.

Key Features

• AISI Type O1 oil-hardening tool steel for reliable heat-treat response
• Thickness tolerance of plus or minus 0.001 inches for precise pre-hardened dimensions
• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.5 inches for consistent bar length
• Squareness: edge 0.003 inches, end 0.004 inches per inch of thickness
• Sold as a single piece with no minimum order beyond one unit

Compatibility

Designed as a standard O1 oil-hardening tool steel flat bar suitable for tool and die applications, fixture fabrication, and general machine shop use where AISI Type O1 material specification is required.

Installation Notes

Cutting, grinding, and machining should be performed in the annealed state prior to hardening. Oil-quench heat treatment should be carried out by qualified personnel following established metallurgical procedures and applicable shop safety standards. Always use appropriate personal protective equipment when cutting or grinding tool steel. Consult material data sheets for specific heat-treat cycles before processing.
