Hertel C.E03.0462 Aircraft Extension Drill Bit 14 Hss

Product Description

The HERTEL C.E03.0462 is a wire gauge size 14 aircraft extension drill bit designed for reaching into recessed or tight access locations where a standard-length drill cannot reach. Built from high-speed steel (HSS) with an oxide finish, this bit delivers reliable performance in general-purpose drilling applications across metal, composites, and similar materials. The 135-degree split point is self-centering, reducing the need for a center punch and minimizing walking on entry. A web-thinned, tapered web configuration reduces cutting resistance for cleaner, faster penetration. The straight cylindrical shank seats securely in standard drill chucks. This bit is typically installed and used by aircraft maintenance technicians, sheet metal workers, and structural fabricators.

This aircraft extension drill bit is suited for structural and maintenance applications where extended reach is required. At 6 inches overall length with a 2.1875-inch spiral flute, it handles drilling through layered assemblies, structural frames, and panels in aerospace and industrial settings. The right-hand cutting direction and two-flute spiral geometry promote efficient chip evacuation during use. It conforms to NAS 907 standards, making it appropriate for aerospace-grade work and quality-controlled fabrication environments.

Key Features

• Wire gauge size 14 (0.1820 inch decimal equivalent) for precise, standardized hole sizing
• 135-degree split point is self-centering and reduces drill walking on entry
• Web-thinned tapered web lowers cutting resistance for faster penetration
• High-speed steel construction with oxide finish for durability in general-purpose metal drilling
• 6-inch overall length provides extended reach into confined or recessed areas
• Conforms to NAS 907 aerospace drill bit standards

Compatibility

Designed as an OEM-style replacement and general-use aircraft extension drill bit compatible with standard straight-shank drill chucks used in aerospace maintenance, structural fabrication, and industrial drilling applications.

Installation Notes

This bit is typically used by aircraft maintenance technicians, sheet metal workers, and industrial machinists. Secure the straight cylindrical shank fully into the drill chuck before operation and verify chuck tightness before drilling. Always wear appropriate eye protection and follow applicable shop safety and worksite protocols when operating drilling equipment. Inspect the cutting edges for wear or damage before each use and replace if the point shows signs of dulling or chipping.
