Built from high speed steel (HSS) with an oxide finish, it measures 0.104 inches (wire size 37) in diameter with a straight-cylindrical shank of the same diameter. The 135-degree split point is self-centering and web-thinned, eliminating the need for a center punch and reducing walking on entry. With a spiral flute length of 1.4375 inches and a 4xD flute-to-diameter ratio, this bit evacuates chips effectively while maintaining stability in deeper bores. It weighs approximately 0.04 pounds.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for production and maintenance work in aerospace, aviation, and general fabrication environments where extended reach and precise sizing are required. The aircraft extension configuration allows access to recessed or obstructed hole locations that standard-length drill bits cannot reach. It is used by aircraft maintenance technicians, sheet metal workers, and general machinists working with steel, aluminum, and similar materials. The general-purpose tool performance rating makes it appropriate for a wide range of shop and field drilling tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 37 (0.104 inches diameter) straight-cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with self-centering geometry reduces walking and eliminates center-punch requirement\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web construction lowers thrust force and improves chip clearance\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with oxide finish for corrosion resistance and reduced friction\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting, two-flute spiral design for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 Type B standard for aircraft drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit drill bit for use in any right-hand rotating drill press, hand drill, or CNC drilling spindle accepting a 0.104-inch straight-cylindrical shank.
