Hertel C.E06.0462 Aircraft Extension Drill Bit No. 14

Product Description

The HERTEL C.E06.0462 is a No. 14 wire-size aircraft extension drill bit engineered for deep-reach drilling in tight or hard-to-access locations. Built from cobalt high-speed steel and finished with a straw coating for heat resistance, this bit delivers reliable performance in tough materials including stainless steel, high-temperature alloys, and hardened steels. The 135-degree split point is self-centering and eliminates the need for a center punch on most surfaces, reducing setup time. At 6 inches overall length with a 2.1875-inch spiral flute, it gives machinists and maintenance technicians the reach and chip evacuation needed in extended drilling applications.

This bit is suited for aircraft maintenance, aerospace fabrication, and general industrial applications where standard-length bits cannot reach. It excels in structural work, sheet metal stacks, and confined drilling scenarios common in MRO environments. The straight cylindrical shank fits standard drill chucks without adapters, and the right-hand cutting direction is compatible with all conventional drill presses, hand drills, and pneumatic drills. General-purpose tool performance makes it a practical choice across production and field repair settings.

Key Features

• Cobalt construction for heat and wear resistance in hard and abrasive materials
• 135-degree split point is self-centering and reduces walking on flat surfaces
• Straw finish provides additional thermal protection during high-speed drilling
• Extended 6-inch overall length enables deep-reach and confined-space drilling
• 2-flute spiral design with tapered web thinning improves chip evacuation
• Meets NAS 907 standard for aircraft-grade drill bit performance

Compatibility

Designed as a general-purpose aircraft extension drill bit with a straight cylindrical shank, compatible with standard drill chucks accepting a 0.182-inch diameter shank.

Installation Notes

Installation and use of this bit is typically performed by machinists, aircraft maintenance technicians, and industrial tradespeople. Secure the shank fully in the chuck before use and verify the workpiece is properly clamped. Use appropriate cutting fluid when drilling high-strength or heat-sensitive alloys to extend bit life. Inspect the cutting edges before each use and replace if chipping or heat discoloration is present on the flutes.
