A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and its balance of toughness and wear resistance. This flat stock ships in its annealed condition, ready for machining, grinding, and subsequent heat treat to working hardness. Machinists, tool-and-die makers, and metalworking shops use this material to fabricate punches, dies, gauges, and precision tooling components. At 1.21 pounds per piece, the bar is manageable for bench work and small fixture builds.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for cold-work tooling applications in job shops, tool rooms, and production machining environments. Typical uses include blanking dies, forming tools, shear blades, and drill jigs where dimensional accuracy and predictable air-hardening response are required. The bar is supplied to close tolerances, making it appropriate for applications where near-net-shape stock is preferred to reduce grinding time.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel  -  stable geometry through heat treat cycle\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus or minus 0.062 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: edge 0.003 inches and ends 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003eAnnealed condition  -  ready for machining before hardening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat bar for use in cold-work tooling, die making, and precision machining applications where 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 or tool-and-die personnel using appropriate speeds, feeds, and cutting fluids for tool steel. Heat treatment to working hardness should follow the material supplier's recommended austenitizing and air-quench procedure for A2 steel. Always allow the bar to reach ambient temperature before precision grinding. Secure workpieces properly in vises or fixtures before any cutting operation.\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: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 5\/8 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 minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus or minus 0.062 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: Edge 0.003 inches and Ends 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.21 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: 85998318\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51991048945970,"sku":"85998318","price":86.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_c613dd59-3fa4-4b93-ad08-8bdf6a5d3d82.jpg?v=1789989404","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-85998318-a2-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
