Built from high-speed steel with an oxide finish, it carries a No. 19 wire gauge size (0.1660 inches decimal) and measures 12 inches in overall length. The 135-degree split point is self-centering and web-thinned, which reduces thrust during entry and minimizes walking on hard or curved surfaces. Two spiral flutes with a 2.125-inch flute length clear chips efficiently during drilling. This bit is installed by machinists, aircraft maintenance technicians, and sheet metal workers requiring extended reach without sacrificing hole accuracy.\u003c\/p\u003e\u003cp\u003eThis extension drill bit is suited for aerospace, automotive, and general fabrication work where standard-depth bits fall short. The straight cylindrical shank seats securely in drill chucks and right-angle drill attachments commonly used in tight aircraft airframe bays and structural assemblies. The general-purpose tool performance rating makes it appropriate for use on aluminum, mild steel, and similar materials encountered in production and repair environments. Right-hand cutting direction is standard for use with conventional drill presses, cordless drills, and pneumatic drill motors.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 19 wire gauge size at 0.1660 inches decimal diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e12-inch overall length provides extended reach into deep or restricted work areas\u003c\/li\u003e\n\u003cli\u003e135-degree split point is self-centering and reduces bit walking on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web configuration lowers drilling thrust and improves chip evacuation\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction with oxide finish for wear resistance in general-purpose applications\u003c\/li\u003e\n\u003cli\u003eMeets NAS 907 standard for aircraft-quality drill bit performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose aircraft extension drill bit with a straight cylindrical shank compatible with standard drill chucks and right-angle drill motor attachments used in aerospace and fabrication applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is typically installed by machinists and aircraft maintenance technicians using drill presses, pneumatic drill motors, or cordless drills.
