AISI Type A2 tool steel offers good wear resistance, dimensional stability during heat treatment, and moderate toughness, making it a reliable choice for punches, dies, gauges, and cutting tools. This bar measures 5\/16 inches thick by 1-1\/4 inches wide by 18 inches long and ships at approximately 1.99 pounds. Thickness and width tolerances are held to +0.010 to 0.015 inches, with a length tolerance of +0.062 inches and a squareness tolerance of +\/-0.003 inches. Machinists, tool and die makers, and metalworking shops are the primary users.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for low-to-medium production tooling in job shops, tool rooms, and industrial maintenance environments. It is used to fabricate punches, forming dies, trim dies, jigs, fixtures, and wear plates where air-hardening steel is preferred over oil-hardening grades. The air-hardening characteristic of A2 reduces distortion risk during hardening, which is valuable when machining close-tolerance components before heat treatment. This bar size is appropriate for smaller tooling components and can be cut to length on a band saw or surface-ground to final dimensions prior to hardening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type A2 air-hardening tool steel  -  reduces distortion during heat treatment compared to oil-hardening grades\u003c\/li\u003e\n\u003cli\u003eThickness: 5\/16 inches with tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eWidth: 1-1\/4 inches with tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eOverall length: 18 inches with tolerance of +0.062 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance held to +\/-0.003 inches for precise fit-up in tooling applications\u003c\/li\u003e\n\u003cli\u003eReady-to-machine flat stock format  -  suitable for sawing, milling, and grinding prior to hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose A2 air-hardening tool steel flat bar for use in tool and die fabrication, fixture building, and precision machining applications requiring AISI A2 material specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining should be performed by qualified machinists or tool and die makers using appropriate metalworking equipment. Follow established heat-treatment procedures for AISI A2 tool steel, including proper preheat, hardening, and double-tempering cycles per the material specification. Always wear appropriate PPE when cutting or grinding tool steel. Consult the material manufacturer's data sheet for specific heat-treatment parameters before processing.\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 Type A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/4 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\u003eLength Tolerance\u003c\/strong\u003e: +0.062 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: +\/-0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.99 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: DRILL ROD TOOL STEELS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 06320121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51959678697778,"sku":"06320121","price":104.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_89e46672-8f5b-4161-87d0-d6d9a63ddd1b.jpg?v=1789945832","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-06320121-a2-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
