Hertel C.E03.0595 Aircraft Extension Drill Bit 15/64 in

Product Description

The HERTEL C.E03.0595 is an aircraft extension drill bit engineered for professionals who need extra reach in confined or deep-bore applications. Built from high-speed steel with an oxide finish, it measures 15/64 inch (0.2344 inch decimal) in diameter and runs 6 inches in overall length. The 135-degree split point is self-centering, reducing the need for a center punch and minimizing walking on entry. The web-thinned, tapered web configuration reduces thrust and cutting resistance. With a 2-5/8 inch spiral flute and right-hand cutting direction, it evacuates chips efficiently in both metal and composite materials. This bit is a go-to for aviation maintenance technicians, millwrights, and general-purpose machinists.

This aircraft extension drill bit is suited for applications requiring additional clearance beyond what a standard-length bit provides. Its extended 6-inch overall length makes it practical for reaching recessed holes, blind bores, or fastener locations in tight assemblies found in aircraft structures, HVAC sheet metal, electrical enclosures, and light fabrication work. The straight cylindrical shank fits standard drill chucks without adapters. It is a general-purpose bit appropriate for a broad range of metalworking and maintenance tasks.

Key Features

• 135-degree split point is self-centering for accurate starts without a center punch
• Web-thinned tapered web reduces cutting thrust and extends tool life
• High-speed steel construction with oxide finish for corrosion resistance and lubricity
• 6-inch overall length provides extended reach for confined or deep-access locations
• 2-flute spiral design promotes efficient chip evacuation during drilling
• Right-hand cutting, straight cylindrical shank compatible with standard drill chucks

Compatibility

Designed as a general-purpose aircraft extension drill bit compatible with any standard drill chuck accepting a straight cylindrical shank in the 15/64 inch diameter range.

Installation Notes

Installation should be performed by a qualified machinist, maintenance technician, or aviation mechanic following applicable shop safety procedures. Secure the workpiece firmly before drilling and ensure the chuck is tightened completely before operation. Always wear appropriate eye protection and follow applicable OSHA and shop-specific standards when operating drilling equipment. Inspect the bit for wear or damage before each use and remove from service if the cutting edges are chipped or the flutes are clogged.
