A2 tool steel is a versatile cold-work die steel known for its balanced combination of wear resistance and toughness after air hardening. This flat stock is held to tight dimensional tolerances, including plus or minus 0.001 inches on thickness and plus or minus 0.003 inches on squareness, making it suitable for toolmaking, die work, and precision machining applications. Machinists, tool and die makers, and metalworking professionals are the primary users of this material.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in tool and die shops, maintenance and repair operations, and fabrication environments where dimensional accuracy is critical before and after heat treatment. A2 tool steel responds well to air hardening, reducing the risk of distortion compared to oil- or water-hardening grades. It is well suited for punches, dies, forming tools, gauges, and similar components that require a consistent cross-section and predictable heat-treat response. The 36-inch length provides usable stock for a range of small to medium tooling projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for reduced distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to plus 0.005 inches for controlled oversizing\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.003 inches across the cross-section\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus or minus 0.250 to 0.500 inches on the 36-inch bar\u003c\/li\u003e\n\u003cli\u003eReady-to-machine flat stock format for toolmaking and die applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock suitable for general 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, grinding, and machining of tool steel flat stock should be performed with appropriate personal protective equipment and tooling rated for hardened or semi-hardened steel. Heat treatment should be performed by qualified personnel following established procedures for AISI A2 steel, including proper austenitizing temperature ranges and controlled air cooling. Avoid contact with water or oil quench media during hardening unless the process has been specifically adapted. Verify final dimensions after any heat treatment cycle before use in precision tooling applications.\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: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.75 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 plus 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: 1.91 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: 03718129\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51972302471474,"sku":"03718129","price":114.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_64fe3faa-d132-478e-9ded-0ae5b697939c.jpg?v=1789965850","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-03718129-a2-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
