Manufactured to AISI Type O1 specifications, this flat stock measures 1\/32 inch thick, 3 inches wide, and 36 inches long, with a thickness tolerance of +\/- 0.001 inches. O1 tool steel is a widely used oil-hardening grade known for its dimensional stability during heat treatment, good machinability in the annealed state, and ability to hold a sharp edge after hardening. Machinists, tool and die makers, and fabricators stock this material for producing punches, dies, gauges, and precision fixtures.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is suited for machine shops, tool rooms, and fabrication environments requiring close-tolerance stock in the annealed condition ready for machining and subsequent oil-hardening heat treatment. The 36-inch length provides practical cut-down stock for multiple workpiece blanks. The 3-inch width accommodates a broad range of tool and die blank profiles without excess material removal. Each piece ships as a single unit at 0.96 pounds, making it practical for bench-scale and production toolroom use alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type O1 oil-hardening tool steel — stable dimensions through heat treatment cycle\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of +\/- 0.001 inches for close-fit toolroom applications\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of +0.015 inches, width tolerance of 0.000 to -0.005 inches\u003c\/li\u003e\n  \u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n  \u003cli\u003eSupplied in annealed condition — machines with standard HSS or carbide tooling\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging with no minimum order above one unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard O1 oil-hardening flat stock for general toolroom and die-making use where AISI Type O1 material specification is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting and machining should be performed in the annealed state prior to heat treatment. Oil-hardening heat treatment requires controlled furnace equipment and proper quenching technique — follow established metallurgical procedures or consult a qualified heat treater. Wear appropriate PPE when cutting, grinding, or handling tool steel stock with sharp edges. Secure workpieces firmly in a vise or fixture before machining to maintain dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI Type O1 Oil Hardening\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: +\/- 0.001 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: 0.000 to -0.005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: Edge: All 0.003 inches per inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.96 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 59147\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541565636914,"sku":"59147","price":256.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_81d503e3-5ce8-4487-b656-791e8993a228.jpg?v=1785879284","url":"https:\/\/voomisupply.com\/products\/starrett-59147-o1-tool-steel-flat-stock-1-32x3x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
