A2 tool steel offers excellent dimensional stability during heat treatment, making it a preferred choice for toolmakers, machinists, and die makers who need consistent geometry after hardening. This flat stock ships in ready-to-machine condition and is held to tight tolerances: plus or minus 0.001 inches on thickness, plus 0.000 to 0.005 inches on width, and plus or minus 0.250 to 0.500 inches on length. At 11.47 pounds per piece, it is suitable for benchtop and machine-vise work without additional handling equipment.\u003c\/p\u003e\u003cp\u003eA2 air-hardening flat stock is used in the fabrication of dies, punches, gauges, forming tools, and fixtures where controlled heat treatment and minimal distortion are required. It is a standard material choice in tool-and-die shops, maintenance repair operations, and precision machining environments. The 36-inch length allows for multiple blanks to be cut from a single bar, reducing material waste on typical tooling projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel  -  minimal distortion during heat treat cycles\u003c\/li\u003e\n\u003cli\u003eThickness tolerance held to plus or minus 0.001 inches for tight fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches for predictable finishing allowance\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.003 inches across the cross-section\u003c\/li\u003e\n\u003cli\u003e36-inch bar length supports multiple blanks from a single piece\u003c\/li\u003e\n\u003cli\u003eReady-to-machine condition  -  no pre-processing required before layout or cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 tool steel flat stock suitable for die making, punch fabrication, gauge construction, and general tooling applications where air-hardening steel stock is specified.\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 toolmakers using appropriate coolant and tooling rated for hardened or semi-hardened steel. Heat treatment of A2 tool steel should follow the material manufacturer's recommended austenitizing and tempering cycles  -  do not substitute generic heat treat procedures. Always use proper personal protective equipment when cutting, grinding, or handling steel bar stock. Ensure workholding fixtures are rated for the material weight before beginning machining operations.\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: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\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 or minus 0.250 to 0.500 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\u003eWeight\u003c\/strong\u003e: 11.47 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: 03718590\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51972024238386,"sku":"03718590","price":306.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_60b18b64-18b8-4680-9a59-b0bbd83e1ad6.jpg?v=1789961301","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-03718590-a2-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
