The HERTEL C.E06.0218 is a wire gauge size 44 aircraft extension drill bit designed for precise, high-performance drilling in demanding applications. Built from cobalt tool steel, it delivers superior heat and wear resistance compared to standard high-speed steel bits. The 135-degree split point is self-centering, eliminating the need for a center punch and reducing walking on entry. A straw finish indicates controlled heat treatment. With a 6-inch overall length and a 0.0860-inch decimal diameter, this bit gives technicians extended reach into confined or deep workspaces. Licensed HVAC, plumbing, and general trade professionals working with tight-clearance installations will find this geometry well suited to precision hole placement.
This aircraft extension drill bit is built for general-purpose drilling where extended reach and accuracy are required. The spiral flute with two flutes and a right-hand cutting direction efficiently evacuates chips during operation. The web-thinned, tapered web configuration reduces thrust and improves penetration in ferrous and non-ferrous materials. It meets NAS 907 standards, making it appropriate for aerospace-grade and precision trade applications. The straight cylindrical shank seats securely in standard drill chucks without slippage.
Designed as a general-purpose aircraft extension drill bit compatible with standard straight-cylindrical chuck systems used across trade and precision drilling applications.
This bit is installed and operated by machinists, sheet metal workers, and trade professionals using standard handheld or drill press equipment. Secure the straight cylindrical shank fully in the chuck before operating. Use appropriate cutting fluid when drilling hard or ferrous materials to extend bit life and maintain dimensional accuracy. Inspect the cutting edges before each use and discard the bit if chipping or heat discoloration beyond the straw zone is observed.
