O1 tool steel is a general-purpose cold-work steel that responds well to oil quenching, making it a standard choice for dies, punches, gauges, and precision tooling components. This flat stock is supplied in the annealed condition, ready for machining and subsequent heat treatment. Thickness tolerance is held to plus or minus 0.001 inches, and squareness is controlled to 0.003 inches per inch on all edges, reflecting the tight dimensional standards required by toolmakers and precision machinists.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in tool-and-die shops, machine shops, and maintenance departments for fabricating cutting tools, jigs, fixtures, and wear components. The 36-inch length provides ample stock for multiple part blanks from a single bar. It is suited to both production tooling applications and one-off precision parts where consistent hardening response is required. Machinists, tool and die makers, and industrial maintenance technicians are the typical end users for this material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable, controllable heat treatment response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for high-precision blank stock\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches, zero minus, providing full usable length\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches for consistent fit in close-tolerance applications\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e36-inch bar length yields multiple blanks per piece, reducing material waste\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat bar suitable for general toolmaking, die work, and precision machining applications requiring AISI Type O1 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed with appropriate coolant to maintain dimensional accuracy and avoid surface hardening from heat buildup. Heat treatment of O1 steel requires controlled furnace conditions and oil quench media; follow the material manufacturer guidelines and applicable shop safety practices. Personal protective equipment including eye protection and heat-resistant gloves is required during all cutting and heat-treat operations. Consult applicable OSHA and shop safety codes before processing.\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: 3 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 minus 0.005 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: 30.6 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: 54505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543084499250,"sku":"54505","price":940.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_63dccfa9-4778-4531-b093-19f5e7f2fd53.jpg?v=1785915177","url":"https:\/\/voomisupply.com\/products\/starrett-54505-o1-tool-steel-flat-stock-1x3x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
