Measuring 1-1\/4 inches thick, 6 inches wide, and 18 inches long, this flat stock ships in an annealed condition with tight dimensional tolerances: +0.010 to 0.015 inches on thickness, width, and squareness, and +0.25 inches on length. A2 tool steel offers a balanced combination of wear resistance and toughness, making it a widely used choice for dies, punches, gauges, and precision tooling components.\u003c\/p\u003e\n\u003cp\u003eThis flat stock is suited for machine shops, tool and die operations, and industrial maintenance environments where custom tooling is fabricated in-house. Because the blank arrives with close tolerances on all critical dimensions, it is ready for surface grinding, milling, or EDM work with minimal stock removal required. The 18-inch length provides sufficient material for multiple small tools or a single large die component. It is appropriate for both job shops and in-plant toolrooms handling medium- to high-production tooling demands.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA2 air-hardening tool steel (AISI Type A2) for dimensional stability during heat treatment\u003c\/li\u003e\n  \u003cli\u003eTight thickness tolerance of +0.010 to 0.015 inches reduces grinding stock allowance\u003c\/li\u003e\n  \u003cli\u003eWidth and squareness tolerances of +0.010 to 0.015 inches support accurate layout and machining\u003c\/li\u003e\n  \u003cli\u003eLength tolerance of +0.25 inches provides a consistent saw-cut allowance\u003c\/li\u003e\n  \u003cli\u003ePre-cut 1-1\/4 inches x 6 inches x 18 inches blank eliminates rough sawing from bar stock\u003c\/li\u003e\n  \u003cli\u003eSuitable for dies, punches, gauges, forming tools, and precision jig components\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose A2 tool steel flat blank for use in any tool and die or machining application requiring AISI A2 air-hardening material in a 1-1\/4 inches x 6 inches x 18 inches profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with air-hardening steels. The steel should be stress-relieved after rough machining and before finish grinding to minimize distortion. Always follow the material manufacturer's published heat treatment guidelines for austenitizing temperature, soak time, and air-cool procedure. Proper eye and hand protection is required during all cutting, grinding, and handling 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 A2 Air-Hardening\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquareness Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 37.79 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 57663\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541666070834,"sku":"57663","price":1948.04,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_14c3e88b-dd06-4757-84ca-822fa482d911.jpg?v=1785881593","url":"https:\/\/voomisupply.com\/products\/starrett-57663-a2-tool-steel-flat-stock-1-1-4x6x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
