Drill Rod Tool Steels 809282 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 809282 is an O1 oil-hardening tool steel flat stock bar cut to 3/64 inches thick, 1 inch wide, and 18 inches long. AISI Type O1 tool steel is a general-purpose oil-hardening grade prized for its dimensional stability during heat treatment, good machinability in the annealed state, and ability to hold a sharp edge after hardening. This flat stock ships in the annealed condition, ready for machining, grinding, or filing to final shape before hardening. Machinists, toolmakers, and die makers use it to fabricate punches, dies, gauges, and cutting tools where close tolerances and reliable hardenability are required.

O1 flat stock in this size range is well suited for small tooling applications in job shops, tool and die operations, and maintenance departments. The 18-inch length provides enough stock for multiple short tooling blanks, while the 1-inch width covers a broad range of punch and die applications. The 3/64-inch thickness makes this bar appropriate for thin blade, shim-style, or detail tooling work where a compact cross section is needed.

Key Features

• AISI Type O1 oil-hardening tool steel for predictable hardening response in an oil quench
• Annealed condition allows machining, grinding, and filing prior to heat treatment
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal calculations
• Width tolerance of plus 0.005 inches, minus 0.000 inches ensures the bar is never undersize
• Length tolerance of plus 0.250 inches provides adequate face-up stock on cut ends
• Squareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends

Compatibility

Designed as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for general toolmaking, die making, and precision machining applications where an oil-quench hardenable steel in flat bar form is required.

Installation Notes

Cutting, grinding, and machining should be performed while the bar is in the annealed condition before any hardening operation. Heat treatment, including austenitizing temperature, quench medium, and tempering cycle, must follow established metallurgical guidelines for AISI O1 tool steel and should be performed by qualified personnel using appropriate equipment. Always use proper personal protective equipment when cutting or grinding tool steel. Dispose of grinding swarf and cutting fluids in accordance with applicable local regulations.
