It measures 1\/16 inch thick, 1-1\/4 inches wide, and 18 inches long, and ships in annealed condition ready for machining. Thickness and squareness tolerances are held to plus or minus 0.001 inch, while width tolerance is held to plus 0.000 to 0.005 inch. These tight tolerances reduce setup time when the stock is used as a direct-grind blank.\u003c\/p\u003e\u003cp\u003eA2 tool steel is a general-purpose air-hardening grade suited for low-distortion heat treatment. This flat stock format is commonly used in toolroom and maintenance shop environments for fabricating or repairing stamping dies, form punches, blades, and precision gauging fixtures. Its moderate size makes it appropriate for both benchtop machining and surface grinding operations. Shops working with short-run tooling or prototype fixtures will find this bar stock a practical starting point.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel — low distortion during heat treatment compared to oil-hardening grades\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inch for consistent stock removal when grinding\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inch\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inch — allows for facing or parting to final dimension\u003c\/li\u003e\n\u003cli\u003eAnnealed condition suitable for machining, drilling, and grinding prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard toolroom flat stock blank compatible with conventional machining, surface grinding, EDM, and heat-treatment processes typical of A2 tool steel applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel should be performed by qualified toolmakers or machinists familiar with A2 grade processing requirements. Always secure the workpiece properly before cutting or grinding operations. Heat treatment, including hardening and tempering, should follow the steel producer's recommended thermal cycle for A2 tool steel. Use appropriate personal protective equipment when grinding or handling sharp-edged stock.\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 A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.25 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: plus or minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to 0.005 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.39 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: 57492\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540058571058,"sku":"57492","price":84.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_1d431d19-0183-4404-8ca9-7ae2da0523c0.jpg?v=1785846026","url":"https:\/\/voomisupply.com\/products\/starrett-57492-a2-tool-steel-flat-stock-1-16-x-1-1-4-x-18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
