Hertel C.E03.0208 Aircraft Extension Drill Bit 45 Hss

Product Description

The HERTEL C.E03.0208 is a wire gauge #45 aircraft extension drill bit designed for precision drilling in aerospace and industrial applications. Made from high-speed steel with an oxide finish, this bit features a 135-degree split point that is self-centering and reduces walking on entry. The two-flute spiral design with web thinning and a tapered web configuration promotes chip evacuation and reduces thrust during drilling. At 6 inches overall length, it gives technicians the reach needed for drilling in confined or deep-access locations. It weighs 0.1 pounds and meets NAS 907 standards.

This drill bit suits general-purpose drilling in metal, aluminum, and composite materials commonly encountered in aircraft maintenance and sheet metal fabrication. The 6-inch extended length makes it well suited for reaching boltholes and rivet locations that standard-length bits cannot access. Machinists, aircraft maintenance technicians, and sheet metal workers typically deploy this bit when working within airframes, panels, or structural assemblies where clearance is limited.

Key Features

• Wire size #45 (0.0820 inches decimal) straight cylindrical shank for standard chuck compatibility
• 135-degree split point with self-centering geometry reduces walk and improves hole accuracy
• Web-thinned, tapered web construction lowers drilling thrust and extends bit life
• High-speed steel construction with oxide finish for corrosion resistance and reduced friction
• 6-inch overall length provides extended reach in confined or deep-access drilling scenarios
• Meets NAS 907 standard for aircraft-grade tooling

Compatibility

Designed as a general-purpose aircraft extension drill bit for use in standard straight-shank chucks compatible with a 0.0820-inch diameter shank. Suitable for drilling applications conforming to NAS 907 requirements.

Installation Notes

This bit is installed by a machinist or aircraft maintenance technician using a standard drill motor or drill press with a chuck rated for the 0.0820-inch straight shank diameter. Secure the workpiece and verify chuck engagement before operation. Right-hand cutting direction requires standard forward rotation. Follow applicable shop safety practices and manufacturer guidelines when drilling composite or hardened materials.
