Built from high-speed steel with an oxide finish, this bit measures 12 inches in overall length and features a 135-degree split point with web thinning for improved centering and reduced thrust on entry. The 0.0410 inch decimal diameter, two-flute spiral configuration, and straight cylindrical shank make it a practical choice for technicians and machinists who need extended reach in confined or deep-hole drilling scenarios. This bit meets NAS 907 standards and is suited for general-purpose use in metal and composite materials.\u003c\/p\u003e\u003cp\u003eAircraft extension drill bits like the C.E04.0104 are used in aerospace MRO, sheet metal fabrication, and structural assembly work where standard-length bits cannot reach. The extended 12-inch overall length allows drilling through bulkheads, panels, and structural members without repositioning. The right-hand spiral flute with a 0.6875 inch flute length channels chips away from the cutting zone, supporting cleaner holes in tight or restricted spaces. This bit is typically used by aircraft mechanics, sheet metal workers, and precision machinists in both production and repair environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 59 wire gauge size, 0.0410 inch decimal diameter\u003c\/li\u003e\n\u003cli\u003e135-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003e12-inch overall length for extended reach in confined drilling applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for wear resistance\u003c\/li\u003e\n\u003cli\u003eTwo-flute right-hand spiral design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aerospace-grade tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit compatible with standard drill chucks and pneumatic or electric drills accepting a 0.0410 inch straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is intended for use by qualified machinists or aircraft maintenance technicians using appropriate drill equipment. Secure the workpiece firmly before drilling and verify chuck grip on the straight cylindrical shank before operation. Always wear appropriate eye protection and follow applicable workplace safety and aviation maintenance regulations when drilling structural materials.
