Measuring 0.25 inches thick, 8 inches wide, and 36 inches long, this piece ships at 20.62 pounds. A2 tool steel offers good toughness combined with excellent dimensional stability during air-hardening, making it a reliable choice for punches, dies, gauges, and forming tools where tight tolerances must be held through the hardening cycle.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited to professional tool and die shops, fabrication facilities, and industrial maintenance operations that machine and heat-treat their own tooling. It is appropriate for both roughing and finish-machining applications prior to air hardening. The ground flat surfaces and close dimensional tolerances reduce setup time and minimize stock removal at the mill or grinder. Machinists and toolmakers working in production or prototype environments will find the pre-ground condition and AISI A2 specification directly usable for a wide range of cutting and forming tool applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel specification for stable, low-distortion heat treatment\u003c\/li\u003e\n\u003cli\u003eGround flat stock with thickness tolerance of plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches for consistent cross-section\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus or minus 0.250 to 0.500 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches on edges and 0.004 inches per inch of thickness on ends\u003c\/li\u003e\n\u003cli\u003eSingle-piece minimum order quantity suitable for job-shop and prototype use\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 suitable for general tool and die, punch, gauge, and forming tool fabrication where A2 specification material is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel flat stock should be performed by qualified toolmakers or machinists familiar with A2 steel procedures. Secure the workpiece properly before any cutting, grinding, or drilling operation. Follow the material manufacturer's recommended heat-treat cycle for A2 tool steel, including proper austenitizing temperature, air-quench procedure, and double-tempering practice. Do not attempt to weld or flame-cut A2 tool steel without following established preheat and post-heat guidelines appropriate for high-carbon alloy tool steels.\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: 8 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\u003eSquareness\u003c\/strong\u003e: Edge 0.003 inches, Ends 0.004 inches per inch of thickness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 20.62 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: 85999670\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":52057877152050,"sku":"85999670","price":1029.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_2f6892f9-4f30-4030-ab2f-871b688a1dcd.jpg?v=1790039198","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-85999670-a2-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
