Measuring 0.125 inches thick, 0.625 inches wide, and 18 inches long, this flat stock ships to close tolerances: plus or minus 0.001 inches on thickness and square, plus 0.000 to 0.005 inches on width, and plus 0.250 inches on length. AISI A2 tool steel offers good wear resistance and dimensional stability through the air-hardening process, making it a reliable choice for medium-run tooling applications.\u003c\/p\u003e\u003cp\u003eA2 flat stock in this size range is commonly used in tool and die shops, maintenance and repair operations, and precision machine shops. It is suited for applications where a tighter dimensional tolerance and consistent cross-section are needed before hardening and grinding. The 18-inch length allows a machinist or toolmaker to cut multiple blanks from a single piece, reducing material waste on short tooling components. This stock is typically processed by grinding, EDM, or conventional machining prior to heat treatment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good toughness and wear resistance\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003ePrecision flat stock format ready for toolmaking blanks, dies, and gauges\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat stock for general toolmaking, die making, and precision machining applications requiring close-tolerance rectangular bar stock.\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 toolmakers using appropriate personal protective equipment. Secure the workpiece firmly before any material removal operation. Heat treatment of A2 tool steel should follow the material manufacturer's recommended hardening and tempering procedures; improper heat treatment can result in distortion or cracking. Always allow the material to reach ambient temperature before taking final measurements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 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: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.625 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 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 0.250 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\u003eWeight\u003c\/strong\u003e: 0.38 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: 57507\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539515146546,"sku":"57507","price":53.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_ac9d756c-bf40-43b0-ad33-f6fc4fb9d82f.jpg?v=1785842338","url":"https:\/\/voomisupply.com\/products\/starrett-57507-a2-tool-steel-flat-stock-1-8x5-8x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
