Manufactured to AISI Type O1 material specification, this flat stock is machined from tool steel and held to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a squareness tolerance of 0.003 inches per inch on all edges. At 122.38 pounds, this is a heavy-duty bar suited for tool and die shops, machine shops, and industrial fabrication environments. Licensed machinists, toolmakers, and metalworking professionals use this stock to produce punches, dies, gauges, and precision cutting tools.\u003c\/p\u003e\u003cp\u003eThis flat stock is intended for applications that require a machinable tool steel blank that can be hardened in oil after machining. The O1 alloy offers good machinability in the annealed state before heat treatment, making it a common choice for toolroom and production die work. Typical applications include the fabrication of blanking dies, form tools, bushings, and other tooling components where tight dimensional accuracy is required before and after hardening. The large 12-inch width and 36-inch length provide ample material for cutting multiple blanks from a single piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel material specification\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise stock dimensions\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches for reliable cut planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003eSquareness on all edges held to 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eFull 1 inch thick by 12 inches wide by 36 inches long bar for large tooling blanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 oil-hardening tool steel flat stock suitable for toolroom, die-making, and precision machining applications requiring AISI Type O1 material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate metalworking equipment. Secure the workpiece properly before any cutting or milling operation. Heat treatment, including oil hardening, should follow established metallurgical procedures and applicable shop safety protocols. Handle the bar with care given its weight of 122.38 pounds; use mechanical lifting aids where required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eOverall Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: 0.000 to plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 122.38 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 54513\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544087691570,"sku":"54513","price":3379.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_d9fb82b2-e3fc-4b01-ae50-ba09dd3e3f3b.jpg?v=1785923914","url":"https:\/\/voomisupply.com\/products\/starrett-54513-o1-tool-steel-flat-stock-1x12x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
