O1 is an oil-hardening, cold-work tool steel known for its good machinability in the annealed state and its ability to hold a sharp edge after hardening. This flat stock is used by tool and die makers, machinists, and metalworking professionals as raw material for dies, punches, gauges, fixtures, and cutting tools. Thickness tolerance is held to plus or minus 0.001 inches, making this bar suitable for precision tool-making applications where tight dimensional control is required before hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is appropriate for job shop, tool room, and industrial maintenance applications where O1 tool steel is the specified material. It is supplied in the annealed condition and is intended to be machined to final shape before oil-hardening heat treatment. The 1 inch by 12 inch by 18 inch blank provides sufficient material for medium to large die plates, fixture bases, or multiple smaller tooling components cut from a single piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable heat treatment response\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for precise starting dimensions\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.015 inches ensures material is never oversized\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches provides stock allowance for facing operations\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition for machinability prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose O1 tool steel flat stock blank for use in tool and die making, fixture fabrication, and precision machining applications where AISI Type O1 oil-hardening tool steel is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel should be performed by qualified tool and die makers or machinists familiar with O1 steel handling procedures. Always follow established shop safety practices when cutting, grinding, or machining tool steel. Oil-hardening heat treatment requires controlled furnace equipment and appropriate quench media — consult the material specification before processing. Wear appropriate PPE when handling bar stock of this size and weight.\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: 18 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 minus 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 61.2 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: 54224\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541063500082,"sku":"54224","price":2051.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_679f12aa-fcce-44fe-8ee3-4febab2386bf.jpg?v=1785868012","url":"https:\/\/voomisupply.com\/products\/starrett-54224-o1-tool-steel-flat-stock-1x12x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
