The blank measures 3\/32 inch thick, 2 inches wide, and 18 inches long, with a weight of 0.96 pounds. Manufactured to AISI Type O1 specification, this flat stock is supplied in the annealed condition, ready for machining and subsequent oil-quench heat treatment. Dimensional tolerances are held tightly: thickness tolerance is plus or minus 0.001 inches, width tolerance is 0.000 to minus 0.005 inches, and length tolerance is plus 0.250 inches. Edge squareness is held to 0.003 inches per inch. Machinists, toolmakers, and die makers rely on O1 stock for its consistent pre-hardened machinability and predictable oil-quench response.\u003c\/p\u003e\u003cp\u003eO1 tool steel flat stock is well suited for shop-floor toolmaking and prototype tooling in both job shops and production facilities. Typical applications include blanking dies, punches, gauges, form tools, cutting tools, and precision fixtures where close dimensional control before heat treat is required. The 18-inch length accommodates a wide range of tool blanks without additional cutoff waste. This stock is sized for single-piece or small-quantity use with a minimum order quantity of one piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel — consistent heat treat response with oil quench\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for close-tolerance toolmaking\u003c\/li\u003e\n\u003cli\u003eWidth tolerance held to 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eEdge squareness of 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eSupplied annealed for ease of machining prior to hardening\u003c\/li\u003e\n\u003cli\u003eSingle-piece minimum order quantity — no excess material commitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat stock blank suitable for general toolmaking, die making, and precision machining applications where AISI Type O1 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining should be performed in the annealed condition before heat treatment. Use appropriate personal protective equipment and cutting fluids when sawing or milling tool steel. Oil-quench heat treatment should be performed by a qualified heat treater following established procedures for AISI O1 tool steel.
