Value Collection 01018373 Aircraft Extension Drill Bit 37

Product Description

The VALUE COLLECTION 01018373 is a wire gauge size 37 aircraft extension drill bit designed for reaching into deep or confined spaces where standard-length bits cannot access. Built from high-speed steel with an oxide finish, this bit features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. The 12-inch overall length and 1.4375-inch spiral flute make it well suited for drilling through aluminum airframes, sheet metal, and structural materials encountered in aircraft maintenance and fabrication work. It is a general-purpose tool installed by aircraft maintenance technicians, machinists, and metalworkers.

This extension drill bit fits applications where reach is critical, including drilling through fuselage panels, bulkheads, deep bores in fixtures, and other assemblies with limited access. The straight cylindrical shank seats securely in standard drill chucks and right-angle drill attachments commonly used in aviation and sheet metal shops. The two-flute spiral design clears chips efficiently during extended-reach drilling operations.

Key Features

• Wire gauge size 37 (0.1040 inches decimal equivalent) for precision hole sizing
• 12-inch overall length provides extended reach into deep or confined work areas
• 135-degree split point self-centers and reduces bit walking on smooth or curved surfaces
• High-speed steel construction with oxide finish for wear resistance in general-purpose metalworking
• Web-thinned tapered web configuration reduces cutting resistance and improves chip clearance
• Two-flute right-hand spiral design promotes efficient chip evacuation during drilling

Compatibility

Designed as a general-purpose aircraft extension drill bit compatible with any standard drill chuck or right-angle drill drive accepting a 0.1040-inch straight cylindrical shank.

Installation Notes

Aircraft extension drill bits are typically used by aviation maintenance technicians and machinists working under applicable maintenance manuals and shop standards. Ensure the drill and workpiece are securely fixtured before drilling to prevent bit deflection over the extended length. Use appropriate cutting fluid for the material being drilled to extend bit life and improve hole quality. Inspect the bit for chipping or wear before each use, as damaged high-speed steel bits should be replaced before drilling structural components.
