Hertel C.E03.0522 Aircraft Drill Bit 5 Wire 135 Point Hss

Product Description

The HERTEL C.E03.0522 is a wire gauge size 5 aircraft extension drill bit designed for deep-reach drilling applications in metal and structural materials. Built from high-speed steel with an oxide finish, this bit features a 135-degree split point with web thinning for self-centering entry and reduced thrust. The 6-inch overall length gives technicians the reach needed for airframe, sheet metal, and structural drilling tasks where a standard-length bit cannot access the work zone. The two-flute spiral design with a tapered web provides efficient chip evacuation during general-purpose drilling.

This aircraft extension drill bit is suited for metalworking and maintenance applications that require extended reach, including aerospace assembly, structural fabrication, and sheet metal work. The 0.2055-inch decimal diameter corresponds to wire gauge number 5, making it a standard selection for technicians working from NAS 907-referenced hole size charts. It is appropriate for use in both production and field maintenance environments where a straight cylindrical shank and right-hand cutting direction are required.

Key Features

• Wire gauge size 5 (0.2055 inches decimal) for precise hole sizing per NAS 907 standards
• 135-degree split point with self-centering tip reduces walking and eliminates center-punch requirement on most metals
• Web-thinned, tapered web lowers cutting thrust and extends tool life
• 2.5-inch spiral flute length promotes efficient chip evacuation during extended-reach drilling
• High-speed steel construction with oxide finish for general-purpose metal drilling durability
• Straight cylindrical shank fits standard drill chucks without an adapter

Compatibility

Designed as a general-purpose aircraft extension drill bit for right-hand drilling in metal substrates where a wire gauge size 5 diameter and 6-inch overall length are specified.

Installation Notes

This bit is installed and operated by machinists, aircraft mechanics, and sheet metal technicians. Secure the straight cylindrical shank firmly in a compatible drill chuck before use and verify the cutting direction matches the drill motor rotation. Reduce feed rate when breaking through material to prevent bit grab and workpiece damage. Inspect the cutting edges and split point for wear before each use and replace when chipping or dulling is observed.
