The bit measures 12 inches in overall length with a 1.5 inch flute length, giving technicians the reach needed for structural and mechanical applications. Manufactured from high speed steel with an oxide finish, it features a 135-degree split point that is self-centering and web-thinned for reduced thrust and cleaner entry on metal substrates. Right-hand cutting with a spiral flute design, this bit is part of the Series 500-12 line and conforms to NAS 907 Type B standards.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for aerospace, aviation maintenance, and general metalworking applications where extended reach is required. The 12-inch body length makes it a practical choice for drilling through panels, frames, or assemblies where access is restricted. It is used by aircraft maintenance technicians, industrial machinists, and skilled tradespeople working with steel, aluminum, and similar materials. The general-purpose tool performance rating makes it appropriate for production and repair environments alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/64 inch (0.1094 inch decimal) diameter with matching straight-cylindrical shank for positive chuck retention\u003c\/li\u003e\n\u003cli\u003e135-degree split point is self-centering and eliminates the need for a center punch on most metal surfaces\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance and heat buildup\u003c\/li\u003e\n\u003cli\u003e12-inch overall length provides aircraft-grade extension reach in tight or deep access situations\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide finish for corrosion resistance and lubricity\u003c\/li\u003e\n\u003cli\u003eConforms to NAS 907 Type B standard for aircraft-quality drill bit performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for applications requiring a 7\/64 inch diameter, 12-inch extension drill conforming to NAS 907 Type B specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by aircraft maintenance technicians, machinists, and qualified tradespeople using standard 3-jaw or collet-style chucks rated for straight-cylindrical shanks. Secure the shank fully in the chuck before operation and verify drill press or hand drill speed is appropriate for the workpiece material. Always wear appropriate eye protection and secure the workpiece before drilling.
