Built from cobalt high-speed steel, this bit handles tough materials including stainless steel, hardened alloys, and other difficult-to-machine metals. It measures 1\/4 inch in diameter with a 12-inch overall length (OAL), providing the extended reach required for aircraft maintenance, structural fabrication, and similar precision drilling tasks. Machinists, aviation maintenance technicians, and metal fabricators rely on cobalt-grade tooling like this for consistent performance at elevated cutting temperatures.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for applications where standard-length bits cannot reach the work surface. Common uses include drilling through deep structural members, engine bays, fuselage panels, and similar confined or deep-access metalworking scenarios. The cobalt alloy construction maintains cutting edge integrity longer than standard high-speed steel under high-heat conditions, making it a practical choice for production drilling as well as one-off repair work in aerospace and industrial maintenance environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4 inch cutting diameter for standard fastener and rivet hole applications\u003c\/li\u003e\n  \u003cli\u003e12 inch overall length provides extended reach into deep or obstructed work areas\u003c\/li\u003e\n  \u003cli\u003eCobalt high-speed steel construction resists heat buildup and edge wear on hard materials\u003c\/li\u003e\n  \u003cli\u003eAircraft-style extension geometry designed for deep-hole drilling accuracy\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 unit for flexible purchasing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit compatible with standard 1\/4 inch drill chucks and collet systems used in hand drills, drill presses, and pneumatic drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSecure the bit firmly in a properly sized chuck before use and verify the shank is fully seated. Always wear appropriate eye and hand protection when drilling metal. Use cutting fluid or coolant when drilling stainless steel or hardened alloys to extend tool life and improve hole quality. Follow applicable workplace safety and aviation maintenance manual procedures when working on certified aircraft structures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\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: Cobalt High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.24 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: AC712-016-I\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EAGLE CUTTING TOOL","offers":[{"title":"Default Title","offer_id":51233324269874,"sku":"AC712-016-I","price":20.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307620226.png?v=1780097376","url":"https:\/\/voomisupply.com\/products\/eagle-cutting-tool-ac712-016-i-cobalt-aircraft-drill","provider":"Voomi Supply","version":"1.0","type":"link"}
