Hertel C.E06.0516 Aircraft Drill Bit 13/64 Cobalt

Product Description

The HERTEL C.E06.0516 is a cobalt aircraft extension drill bit engineered for drilling through tough, hard-to-reach materials in aerospace, sheet metal, and structural fabrication applications. Built from cobalt high-speed steel with a straw finish, this bit features a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on curved or coated surfaces. The overall length of 6 inches gives technicians the reach needed for extended-access drilling scenarios. With a right-hand spiral flute design and web-thinned, tapered web construction, this bit evacuates chips efficiently and maintains cutting edge integrity under sustained load. Installed by machinists, aircraft mechanics, and fabricators.

This drill bit is suited for general-purpose drilling in aerospace and industrial fabrication environments where extended reach is required. It handles high-strength alloys, stainless steel, and other materials that demand cobalt-grade tooling. The 13/64 inch diameter and straight cylindrical shank make it compatible with standard drill chucks and power feed equipment. The 2-7/16 inch flute length provides adequate chip clearance for moderate-depth holes. It meets NAS 907 standards, confirming dimensional compliance for aerospace tooling applications.

Key Features

• Cobalt high-speed steel construction for heat and wear resistance in hard materials
• 135-degree split point with self-centering geometry reduces walking and eliminates center-punching on most surfaces
• Web-thinned, tapered web reduces cutting resistance and extends tool life
• 6-inch overall length provides extended reach for aircraft and structural applications
• Straw finish provides mild lubricity and heat indicator during cutting
• Meets NAS 907 aerospace tooling standard

Compatibility

Designed as a general-purpose aircraft extension drill bit compatible with standard straight-cylindrical shank drill chucks and power feed drilling equipment used in aerospace, sheet metal, and industrial fabrication applications.

Installation Notes

Install and remove drill bits only with the drilling equipment fully powered off and secured. Ensure the straight cylindrical shank is fully seated and the chuck is tightened before drilling. Use appropriate cutting fluid when drilling high-strength alloys or stainless steel to manage heat and extend tool life. Follow applicable shop safety standards and equipment manufacturer guidelines for speed and feed rates appropriate to the workpiece material.
