Hertel C.E06.0178 Aircraft Drill Bit Wire 50 Cobalt

Product Description

The HERTEL C.E06.0178 is a cobalt aircraft extension drill bit designed for drilling in hard and abrasion-resistant materials where standard-length bits cannot reach. Built to a wire gauge size of 50 (0.0700 inches decimal), it features a 135-degree split point that is self-centering and web-thinned, reducing the need for a center punch and improving entry accuracy. The straw finish indicates heat-treated cobalt construction suited for ferrous metals and aerospace alloys. With a 6-inch overall length and spiral flute geometry, this bit is used by machinists, aircraft mechanics, and industrial technicians working in tight or deep access situations.

This drill bit is intended for general-purpose drilling applications in aerospace, aviation maintenance, and industrial fabrication environments. The extended reach makes it well suited for drilling through aircraft skins, structural members, and assemblies where standard-length tooling cannot access the work area. Right-hand cutting direction is standard for conventional drill press and handheld pneumatic or electric drill use. Meets NAS 907 standards, making it appropriate for regulated aerospace maintenance operations.

Key Features

• Wire gauge size 50 (0.0700 inches) straight-cylindrical shank for standard chuck compatibility
• 135-degree split point with self-centering geometry reduces walking and eliminates center-punch requirement
• Web-thinned, tapered web configuration reduces thrust force during entry
• Cobalt tool material with straw finish provides heat and wear resistance in hard metals
• 6-inch overall length with 1-inch spiral flute for extended-reach drilling
• Meets NAS 907 standard for aerospace drill bit performance

Compatibility

Designed as a general-purpose aircraft extension drill bit compatible with standard straight-shank chucks on handheld drills, drill presses, and pneumatic drilling equipment used in aerospace and industrial applications.

Installation Notes

Installation and use should be performed by qualified machinists or aircraft maintenance technicians familiar with aerospace drilling procedures. Ensure the drill is powered off and secured before changing or inspecting bits. Verify chuck size compatibility with the 0.0700-inch shank diameter before use. Follow applicable aerospace maintenance manuals and NAS standards for drilling procedures, feed rates, and coolant use when working on regulated aircraft structures.
