Built from high speed steel with an oxide finish, this bit measures 0.073 inches in diameter and features a 135-degree split point that is self-centering, reducing the need for a center punch and improving positional accuracy on entry. The 1-inch flute length is engineered to a 4xD ratio for efficient chip evacuation. A licensed HVAC tech, machinist, or aircraft maintenance technician working with thin metal or tight-tolerance holes will find this bit well-suited to controlled, repeatable drilling tasks.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for use in aircraft sheet metal work, precision instrument manufacturing, and general metal fabrication where small-diameter accuracy is critical. The Series 501-6 designation places it within a recognized line of extension-style bits used when standard-length bits cannot reach the work surface. The straight-cylindrical shank provides a secure grip in standard drill chucks and collets. With a right-hand cutting direction and tapered web configuration, it is suited for use in hand drills, drill presses, and CNC equipment handling fine-gauge work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 49 (0.073 inches) diameter for tight-tolerance small-hole applications\u003c\/li\u003e\n\u003cli\u003e135-degree split point with self-centering geometry reduces walking on entry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability across a range of metals\u003c\/li\u003e\n\u003cli\u003eOxide finish improves surface hardness and corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1-inch spiral flute length at 4xD ratio promotes chip clearance in shallow bores\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration reduces thrust force during drilling\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 Type B standards for aircraft-grade drill bits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use drill bit for applications requiring NAS 907 Type B compliant wire-gauge extension bits in size 49 (0.073 inches diameter).\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and used by machinists, aircraft maintenance technicians, and metalworking professionals. Secure the straight-cylindrical shank firmly in a compatible drill chuck or collet before use. Always wear appropriate eye protection and ensure the workpiece is properly clamped before drilling.
