It measures 1\/16 inch thick, 2-1\/2 inches wide, and 36 inches long, with a weight of 1.59 pounds. Manufactured to AISI Type O1 specifications, it holds a thickness tolerance of plus or minus 0.001 inches, making it suitable for applications where close dimensional control is required before hardening. Machinists, tool and die makers, and precision fabricators stock and cut this material for gauges, punches, dies, and similar tooling components.\u003c\/p\u003e\n\u003cp\u003eO1 oil-hardening tool steel is a general-purpose tool steel commonly used in low- to medium-production tooling. This flat stock format is suited for bench or machine sawing, milling, drilling, and grinding prior to heat treatment. After machining to near-net shape, it is hardened in oil and tempered to the desired working hardness. Typical applications include knife blanks, stamps, scribers, lathe tools, and small die sections. This stock length of 36 inches allows multiple blanks to be cut from a single piece, reducing material waste in job-shop and maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAISI Type O1 oil-hardening tool steel for general toolmaking and die applications\u003c\/li\u003e\n  \u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close dimensional control\u003c\/li\u003e\n  \u003cli\u003eWidth tolerance of 0.000 to minus 0.005 inches\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of plus 0.015 inches\u003c\/li\u003e\n  \u003cli\u003eEdge squareness held to 0.003 inches per inch across all edges\u003c\/li\u003e\n  \u003cli\u003e36-inch bar length allows multiple blanks from a single piece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard O1 oil-hardening tool steel flat stock suitable for general toolmaking, die making, and precision fabrication work requiring a pre-hardened or anneal-and-harden workflow.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCut to length using a metal-cutting bandsaw, cold saw, or abrasive cutoff wheel before machining. Machine in the annealed state, then harden by heating to the appropriate austenitizing range and quenching in oil, followed by an immediate temper. Allow the steel to cool to hand-warm before tempering to reduce the risk of cracking. Standard shop safety practices apply, including eye protection and secure workholding during all cutting and grinding operations.\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\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 pounds\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\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: 54264\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540168835378,"sku":"54264","price":174.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6555d28ffd7e02d6cc316d25961d7428_f84fb2e1-0dbf-4ffd-8933-93104d67cc7b.jpg?v=1785847805","url":"https:\/\/voomisupply.com\/products\/starrett-54264-o1-tool-steel-flat-stock-1-16x2-5x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
