Hertel C.E06.0193 Aircraft Drill Bit Wire 48 Cobalt

Product Description

The HERTEL C.E06.0193 is a cobalt aircraft extension drill bit designed for high-performance drilling in demanding materials. Built to a wire gauge size of 48 (0.0760 inches decimal), it features a 135-degree split point that self-centers on contact, reducing the need for a center punch. The straw finish is characteristic of cobalt tooling heat treatment. With a straight cylindrical shank and right-hand spiral flute geometry, this bit is suited for licensed machinists, aviation maintenance technicians, and metalworking trade professionals who require precise, controlled drilling in hard or abrasive materials.

This bit is engineered for aircraft-grade drilling applications where extended reach and accurate hole placement are critical. The 6-inch overall length provides the reach required for structural drilling in airframes and assemblies where standard-length bits cannot access the work zone. The 1-inch flute length handles chip evacuation in shallow-to-moderate depth holes. It is appropriate for use in ferrous metals, stainless steel, titanium alloys, and other hard materials commonly encountered in aviation MRO and precision fabrication environments. General-purpose tool performance rating makes it a practical choice across a range of production and repair tasks.

Key Features

• Wire size 48 (0.0760 inches) for precise hole sizing in aircraft structures
• 135-degree split point with self-centering geometry reduces walking and eliminates center-punch steps
• Cobalt tool material with straw finish for heat and wear resistance in hard metals
• 6-inch overall length provides extended reach for deep or obstructed drilling positions
• Web-thinned tapered web reduces thrust and improves cutting efficiency
• Meets NAS 907 standard for aircraft drill bit performance

Compatibility

Designed as an OEM-style aircraft extension drill bit compatible with standard straight-shank drill chucks and collet systems accepting a 0.0760-inch shank diameter. Meets NAS 907 requirements for aircraft drilling applications.

Installation Notes

Installation of this drill bit is performed by aviation maintenance technicians and precision machinists using compatible drill chucks or collet holders. Secure the straight cylindrical shank firmly in the chuck before operation to prevent slippage. Always wear appropriate eye protection and follow applicable workplace safety standards when operating rotary cutting tools. Inspect the cutting edges for chipping or wear before each use, and replace the bit if the point geometry is compromised.
