Hertel C.E03.0295 Aircraft Drill Bit 32 Wire 6in Hss

Product Description

The HERTEL C.E03.0295 is a high-speed steel aircraft extension drill bit designed for deep-reach drilling applications where a standard-length bit cannot access the work area. Built to wire gauge size No. 32 with a decimal diameter of 0.116 inches, this bit features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. The two-flute spiral design with web thinning and a tapered web configuration promotes efficient chip evacuation. The oxide finish provides corrosion resistance and mild lubricity during cutting operations. Overall length is 6 inches, making it well suited for drilling in confined or extended-reach locations in aircraft structures and similar assemblies.

This bit is used in aerospace, aviation maintenance, and precision fabrication applications where extended reach and accurate hole sizing are required. The straight cylindrical shank fits standard drill chucks. Right-hand cutting direction and general-purpose tool performance rating make it a practical choice for drilling aluminum, mild steel, and similar materials encountered in aircraft repair and sheet metal work. It conforms to NAS 907 standards, which is a common specification in aerospace drill tooling procurement.

Key Features

• Wire gauge size No. 32 with 0.116-inch decimal diameter for precise hole sizing
• 135-degree split point with self-centering geometry reduces layout and setup time
• Web-thinned, tapered web construction improves chip flow and reduces thrust load
• 6-inch overall length provides extended reach into aircraft structures and confined spaces
• Oxide finish for corrosion resistance and reduced friction during cutting
• Conforms to NAS 907 aerospace drill bit standard

Compatibility

Designed as a general-purpose aircraft extension drill bit conforming to NAS 907 standards, suitable for use with standard drill chucks accepting a 0.116-inch straight cylindrical shank.

Installation Notes

This bit is typically installed and used by aviation maintenance technicians, sheet metal workers, and precision fabricators. Secure the straight shank firmly in a keyed or keyless chuck before operation and verify chuck capacity accommodates the 0.116-inch shank diameter. Use appropriate cutting fluid when drilling steel to extend tool life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use, as a damaged split point will compromise self-centering performance and hole accuracy.
