Drill Rod Tool Steels 57914 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57914 is an O1 oil-hardening tool steel flat stock bar sized at 0.25 inches thick, 6 inches wide, and 36 inches long, weighing 15.46 pounds. Conforming to AISI Type O1 material specification, this flat stock is produced to close tolerances: thickness held to plus or minus 0.001 inches, width to plus 0.005 inches and minus 0.000 inches, and length to a plus 0.5 inches tolerance. Machinists, toolmakers, and die makers rely on O1 flat stock for blanks, fixtures, gauges, and tooling components that require oil-quench hardening after machining.

O1 tool steel flat stock is commonly used in job shops, tool and die operations, and maintenance machining environments. This bar is well suited for fabricating punches, dies, cutting tools, jigs, and precision fixture components where dimensional stability before heat treatment is critical. The 6 inches wide by 36 inches long format provides ample material for moderate to large tooling blanks without the need for joining or welding multiple pieces.

Key Features

• AISI Type O1 oil-hardening tool steel for excellent machinability before heat treat

• Width tolerance of plus 0.005 inches, minus 0.000 inches
• Length tolerance of plus 0.5 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Full 36 inches length suitable for multiple blanks from a single bar

Compatibility

Designed as a standard O1 oil-hardening tool steel flat stock suitable for general toolmaking, die making, and precision machining applications requiring oil-quench heat treatment.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate metalworking equipment. Oil-hardening heat treatment of O1 steel must be carried out by a qualified heat treater following established metallurgical procedures. Always use proper personal protective equipment when sawing, milling, or grinding tool steel. Consult applicable shop safety standards and OSHA guidelines before beginning material processing.
