Drill Rod Tool Steels 57786 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 57786 is an O1 oil-hardening tool steel flat stock bar intended for toolmaking, die-making, punches, fixtures, and precision machining applications. Manufactured to AISI Type O1 specification, this flat bar measures 0.5 inches thick, 0.625 inches wide, and 18 inches long and weighs 1.62 pounds. O1 tool steel is known for its consistent machinability in the annealed state and its ability to achieve high hardness through oil-quench heat treatment. Thickness tolerance is held to plus or minus 0.001 inches, making this stock suitable for applications where dimensional precision is critical before and after hardening.

This flat stock is used in job shops, tool-and-die operations, mold shops, and maintenance departments where small-section O1 bar stock is cut, machined, or ground to produce tooling components. The 18-inch length is a standard cut that suits bench-scale toolmaking work. Typical end uses include blanking punches, form tools, gauges, jigs, and small die components. The compact cross-section is well-suited for applications requiring a slender, precise tool steel blank.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable heat-treat response
• Thickness tolerance of plus or minus 0.001 inches for tight dimensional control
• Width tolerance of plus 0.005 inches to minus 0.000 inches
• Length tolerance of plus 0.25 inches
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends
• Ready-to-machine annealed condition typical of O1 flat stock

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for general toolmaking, die-making, and precision machining applications requiring this alloy specification.

Installation Notes

Cutting, grinding, and machining should be performed with tooling rated for hardened or annealed tool steel as appropriate to the stage of fabrication. Heat treatment including oil quenching should be performed by a qualified heat treater following recognized procedures for AISI O1 tool steel. Always wear appropriate PPE when cutting or grinding tool steel bar stock. Consult material safety and handling guidelines before processing.
