Cle-line C23624 Aircraft Extension Drill Bit 7/64 in Hss

Product Description

The CLE-LINE C23624 is an aircraft extension drill bit designed for drilling in hard-to-reach areas where a standard-length bit cannot make adequate contact. Built from high-speed steel with an oxide finish, this bit measures 7/64 inch (0.1094 inch) 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. Web thinning further reduces cutting resistance. It is installed by machinists, aircraft maintenance technicians, and metalworking tradespeople working in confined or deep-access applications.

The C23624 is suited for general-purpose drilling in metal, including structural and sheet stock applications where extended reach is required. The 1.5-inch spiral flute promotes chip evacuation along the full working length. The straight cylindrical shank seats in standard drill chucks without modification. Series 1803 construction follows ASME B94.11M standards, making it appropriate for use in professional shop and field environments.

Key Features

• 135-degree split point is self-centering for accurate hole starts without a center punch
• 6-inch overall length provides extended reach into deep or confined work areas
• High-speed steel construction maintains edge integrity under heat and friction
• Oxide finish improves surface hardness and provides mild corrosion resistance
• Web-thinned tapered web reduces thrust required during cutting
• Right-hand spiral flute efficiently clears chips from the hole
• Meets ASME B94.11M standard for drill bit dimensional conformance

Compatibility

Designed as an OEM-style general-purpose aircraft extension drill bit for use in standard drill chucks accepting a straight cylindrical shank in 7/64 inch diameter.

Installation Notes

Installation is performed by machinists, aircraft maintenance technicians, or metalworking tradespeople using a standard hand drill or drill press. Secure the straight cylindrical shank firmly in the chuck before operation to prevent slipping. Always wear appropriate eye protection and secure the workpiece before drilling. Do not exceed the recommended speed range for the material being drilled, and apply cutting fluid when working in harder metals to extend bit life.
