Measuring 1 inch thick, 3 inches wide, and 36 inches long, this bar is ground to tight dimensional tolerances: plus or minus 0.001 inches on thickness and squareness, plus 0.000 to 0.005 inches on width, and plus 0.25 inches on length. A2 tool steel offers excellent wear resistance and dimensional stability through the hardening process, making it a reliable choice for punches, dies, gauges, and cutting tools. At 35.18 pounds, this is a full-length production bar intended for shop use by machinists and tool and die makers.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, toolrooms, and production facilities that fabricate precision tooling components. Typical applications include blanking dies, forming dies, trim dies, jig components, and wear plates where tight tolerances and consistent hardness response are required. The 36-inch length provides flexibility for layout and cutting to finished part dimensions. A2 air-hardening steel is commonly selected over O1 oil-hardening grades when reduced distortion during heat treatment is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel per AISI material specification for consistent heat treatment response\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise fit in tooling applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches for controlled stock allowance\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches with edge squareness of 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eFull 36-inch length with plus 0.25-inch length tolerance for flexible shop cutting\u003c\/li\u003e\n\u003cli\u003eGround flat stock finish ready for layout, machining, or direct use as wear components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat bar suitable for use in toolmaking, die making, and general precision machining wherever AISI A2 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate band saws, surface grinders, or milling equipment rated for tool steel. Heat treatment to full hardness requires controlled air-quench procedures per the A2 specification and should be performed by a qualified heat treat shop or experienced toolroom personnel. Always de-burr cut edges and handle with care to avoid surface damage that could affect final part tolerances. Follow applicable shop safety practices when grinding or machining hardened or pre-hardened steel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel, AISI Type A2 Air-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: plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 35.18 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: 54705\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541831549234,"sku":"54705","price":1396.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_6d3b6048-adc9-42c7-9dd9-55c233bac3ec.jpg?v=1785886193","url":"https:\/\/voomisupply.com\/products\/starrett-54705-a2-tool-steel-flat-stock-1x3x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
