It carries a 11\/16-inch (0.6875-inch) diameter, a 12-inch overall length (OAL), and a 9-inch spiral flute length, making it well suited for applications where standard-length bits cannot reach. The straight-cylindrical shank and right-hand cutting direction make it compatible with conventional drill chucks. The uncoated HSS construction and web-thinned, tapered web geometry support controlled chip evacuation during extended cuts. Machinists, maintenance mechanics, and industrial tradespeople typically reach for this bit when boring through thick stock or deep structural sections.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for general-purpose use and is rated for a broad material range including aluminum, magnesium, copper, nickel, titanium, and various synthetic materials as primary workpiece materials. Secondary applications include stainless steel, hardened steel, nickel alloys, malleable iron, high-strength bronze, magnesium alloy, reinforced plastics, and steel. Its 12xD flute-to-diameter ratio supports deep penetration with adequate chip clearance, making it a practical choice in fabrication shops, maintenance facilities, and production environments where hole depth is a constraint.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e11\/16-inch (0.6875-inch) diameter with matching straight-cylindrical shank for secure chuck engagement\u003c\/li\u003e\n  \u003cli\u003e12-inch overall length and 9-inch flute length for deep-hole drilling beyond standard reach\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust and easier starting\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, two-flute design promotes efficient chip evacuation in deep cuts\u003c\/li\u003e\n  \u003cli\u003eUncoated high-speed steel construction suitable for a wide range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards; Series 1290 general-purpose grade\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose extra-length drill bit compatible with standard drill chucks accepting an 11\/16-inch straight-cylindrical shank.
