Cle-line C23626 Aircraft Extension Drill Bit 9/64 in Hss

Product Description

The CLE-LINE C23626 is an aircraft extension drill bit designed for drilling in hard-to-reach locations where a standard-length bit cannot reach. Built from high-speed steel with an oxide finish, this bit measures 9/64 inches (0.1406 inches) in diameter and delivers a 135-degree split point for self-centering entry and reduced walking on contact. The extended overall length of 6 inches allows access through deep assemblies, structural panels, and confined spaces common in aerospace, fabrication, and heavy mechanical work. A two-flute spiral design with a tapered, web-thinned web clears chips efficiently during operation. Licensed machinists, aircraft mechanics, and maintenance technicians are the primary users of this bit.

This drill bit is suited for general-purpose drilling applications where extra reach is required. Typical installations include structural steel fabrication, aircraft fuselage and panel work, HVAC ductwork framing, and industrial equipment maintenance. The straight cylindrical shank seats securely in standard drill chucks and right-angle drill attachments. Its 1-3/4 inch flute length handles moderate material thickness while maintaining chip clearance. Right-hand cutting direction is standard for conventional drill press and hand drill operation.

Key Features

• 135-degree split point for self-centering start and reduced thrust
• Web-thinned, tapered web configuration for easier penetration and efficient chip evacuation
• 6-inch overall length provides extended reach into deep or confined assemblies
• High-speed steel construction with oxide finish for heat and wear resistance
• Two spiral flutes with right-hand cutting direction for standard drill compatibility
• Meets ASME B94.11M dimensional standards

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for applications requiring a 9/64-inch straight-cylindrical shank bit with extended reach, compatible with standard drill chucks and right-angle drill attachments accepting a 0.1406-inch diameter shank.

Installation Notes

Installation of this bit is performed by machinists, aircraft mechanics, and maintenance technicians using hand drills, drill presses, or right-angle drill attachments. Always secure the workpiece before drilling and confirm chuck tightness before operation. Use appropriate cutting fluid when drilling hardened or thick stock to extend bit life. Follow applicable workplace safety standards and PPE requirements during all drilling operations.
