Manufactured to AISI Type O1 specifications, this flat stock measures 3\/32 inches thick, 1\/2 inch wide, and 36 inches long, with a thickness tolerance of plus or minus 0.001 inches. The O1 grade offers good machinability in the annealed state and responds well to oil-quench hardening, making it a go-to material for tool and die shops that need consistent, predictable results from raw stock.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating cutting tools, punches, blanking dies, gauges, and similar precision components in both small-shop and production toolroom environments. The 36-inch length allows for efficient cut-to-size work with minimal waste. Machinists, tool and die makers, and metal fabricators working in industrial or maintenance-repair settings are the primary users of this material. Each piece ships individually, with a minimum order quantity of one.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type O1 oil-hardening tool steel for predictable heat-treat response\u003c\/li\u003e\n\u003cli\u003eTight thickness tolerance of plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of 0.000 to 0.005 inches for consistent stock sizing\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.015 inches ensures full usable length\u003c\/li\u003e\n\u003cli\u003eEdge squareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eReady-to-machine annealed condition straight from stock\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI O1 oil-hardening tool steel flat bar suitable for general toolroom use wherever O1 grade flat stock in 3\/32 x 1\/2 x 36-inch dimensions is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate metalworking equipment. When hardening, follow established oil-quench procedures for O1 tool steel and allow parts to temper immediately after quench to reduce the risk of cracking. Always wear appropriate PPE including safety glasses and heat-resistant gloves during any heat-treating operations. Consult applicable shop safety standards and material data sheets 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\u003eThickness\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1\/2 inch\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: plus or minus 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: plus 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: 0.48 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 54279\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542816981298,"sku":"54279","price":81.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_083537c6-f434-44d7-a485-7c629d964652.jpg?v=1785908220","url":"https:\/\/voomisupply.com\/products\/starrett-54279-o1-tool-steel-flat-stock-3-32x1-2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
