Hertel C.E03.0161 Aircraft Extension Drill Bit 52 Hss

Product Description

The HERTEL C.E03.0161 is a wire-gauge size 52 aircraft extension drill bit designed for precision drilling in tight, deep, or hard-to-reach locations. Built from high-speed steel with an oxide finish, this bit measures 0.0635 inches in decimal diameter and carries a 135-degree split point that is self-centering and web-thinned for reduced thrust and cleaner entry. The spiral flute design with a tapered web configuration promotes efficient chip evacuation. It is a right-hand cutting, general-purpose tool intended for use by machinists, aerospace maintenance technicians, and aircraft service professionals who require extended reach without sacrificing hole quality or positional accuracy.

This drill bit is suited for aerospace maintenance, sheet metal work, and general fabrication applications where standard-length bits cannot access the work area. The 6-inch overall length and 0.875-inch flute length make it practical for drilling through assemblies, structural panels, and layered materials in both production and field service environments. It meets NAS 907 standards, making it appropriate for use in aerospace and defense maintenance contexts. The straight cylindrical shank fits standard drill chucks without adapters.

Key Features

• Wire gauge size 52 (0.0635 inches decimal diameter) for precise small-diameter drilling
• 135-degree split point with self-centering geometry reduces walking and improves positional accuracy
• Web-thinned, tapered web construction lowers cutting thrust and extends tool life
• High-speed steel construction with oxide finish provides wear resistance for general-purpose use
• 6-inch overall length delivers extended reach into confined or deep work areas
• Meets NAS 907 standard for aerospace-grade drill bit performance

Compatibility

Designed as a general-purpose aircraft extension drill bit compatible with standard straight-cylindrical shank drill chucks. Suitable for use in aerospace maintenance, sheet metal fabrication, and general machining applications requiring a wire-gauge size 52 bit.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or certified aircraft maintenance technicians following applicable maintenance manual procedures. Secure the straight shank firmly in the drill chuck before operation and confirm the workpiece is properly clamped. Apply appropriate cutting fluid when drilling ferrous materials to reduce heat buildup and extend bit life. Follow all applicable safety standards and shop procedures when operating rotary cutting tools.
