Conforming to AISI Type O1 specifications, this flat stock is manufactured from tool steel and is intended for applications requiring a stock that can be machined, ground, and then oil-quenched to achieve working hardness. Machinists, tool-and-die makers, and metalworking shops use this material to fabricate punches, dies, gauges, and cutting tools. The piece weighs approximately 1.98 pounds and ships as a single bar.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for general tool-and-die work in job shops and production machining environments. Its square cross-section profile and close tolerances make it a practical starting point for custom tooling where dimensional control is critical before and after heat treatment. The 36-inch length provides enough stock to yield multiple shorter tooling blanks from a single piece, reducing setup time and material waste on the shop floor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for controlled heat treatment and good wear resistance in finished tools\u003c\/li\u003e\n\u003cli\u003eSquare cross-section: 7\/16 inches thick by 7\/16 inches wide, suitable for punch and die blanks\u003c\/li\u003e\n\u003cli\u003e36-inch length with a length tolerance of plus 0.5 inches, allowing full usable stock\u003c\/li\u003e\n\u003cli\u003eThickness tolerance held to plus or minus 0.001 inches for consistent grinding stock allowance\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.005 inches to minus 0.000 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: edge 0.003 inches, end 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI Type O1 oil-hardening tool steel flat stock suitable for general toolmaking, die-making, and precision machining applications where oil-quench heat treatment will be performed.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and grinding of tool steel flat stock should be performed by a qualified machinist using appropriate metalworking equipment.
