Designed for drilling in tight or deep access applications, this extended-length bit is built for metalworking tasks that standard-length drills cannot reach. The HSS construction provides the hardness and heat resistance needed for drilling steel, aluminum, and other metals common in aviation, HVAC ductwork, sheet metal fabrication, and general mechanical work. Machinists, aircraft maintenance technicians, and sheet metal workers are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis aircraft drill is suited for production and maintenance environments where reach is a limiting factor. The 12-inch OAL allows drilling through deep structural members, stacked panels, or confined assemblies without repositioning the workpiece. It is commonly used in aerospace maintenance, HVAC installation, electrical conduit work, and industrial fabrication wherever a standard-length bit falls short.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNumber 21 wire gauge diameter for precise hole sizing in metal applications\u003c\/li\u003e\n\u003cli\u003e12-inch overall length provides extended reach in confined or deep-access work areas\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction resists heat buildup during continuous drilling\u003c\/li\u003e\n\u003cli\u003eAircraft-style geometry optimized for drilling metal, including aluminum and mild steel\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 1, available as a single unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard supply item for use with 3\/8-inch or larger keyed and keyless drill chucks accepting wire gauge drill bits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and used by machinists, aircraft maintenance technicians, and sheet metal workers using standard drill equipment. Secure the bit firmly in the chuck and verify runout before drilling. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and maintain hole quality. Follow applicable shop safety procedures including eye protection and securing the workpiece before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Size\u003c\/strong\u003e: Number 21\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EAGLE CUTTING TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A712-121-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233636876594,"sku":"A712-121-I","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620262.png?v=1780105342","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-a712-121-i-hss-aircraft-drill-12-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
