Hertel C.E03.0282 Aircraft Extension Drill Bit 34 Hss

Product Description

The HERTEL C.E03.0282 is a wire size 34 aircraft extension drill bit designed for precision drilling in aerospace and industrial applications. It is manufactured from high-speed steel with an oxide finish, providing heat resistance during high-speed cutting operations. The bit features a 135-degree split point that is self-centering and web-thinned, reducing the need for a center punch and minimizing walking on entry. With a straight cylindrical shank diameter of 0.1110 inches and an overall length of 6 inches, this extension-length bit gives technicians the reach needed to access deep or obstructed bore locations. It is installed by aerospace maintenance professionals, machinists, and industrial trade workers.

This bit is suited for production and maintenance drilling tasks where standard-length bits cannot reach. The 6-inch overall length makes it well-suited for drilling through structural assemblies, bulkheads, and stacked materials in aircraft maintenance and general metalworking environments. The spiral flute geometry and right-hand cutting direction promote efficient chip evacuation during through-hole drilling. General-purpose tool performance makes it appropriate for a range of ferrous and non-ferrous workpiece materials encountered in the field.

Key Features

• Wire size 34 (0.1110 inches decimal) for precision bore sizing
• 135-degree split point with web thinning for self-centering entry without a center punch
• High-speed steel construction with oxide finish for heat and wear resistance
• 6-inch overall length provides extended reach into deep or obstructed locations
• 1.5-inch spiral flute length with tapered web configuration for efficient chip removal
• Right-hand cut, 2-flute design; meets NAS 907 standard

Compatibility

Designed as a general-purpose aircraft extension drill bit conforming to NAS 907, suitable for use in aerospace maintenance, sheet metal fabrication, and industrial metalworking applications requiring extended-length wire-gauge drilling.

Installation Notes

This drill bit is installed by machinists, aerospace maintenance technicians, and industrial drilling professionals. Secure the straight cylindrical shank firmly in a compatible drill chuck before use and verify chuck concentricity to avoid runout. Always wear appropriate eye protection and secure the workpiece before drilling. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.
