Value Collection 261011 Aircraft Extension Drill Bit 11/64

Product Description

The VALUE COLLECTION 261011 is a carbide-tipped aircraft extension drill bit designed for drilling in deep or hard-to-reach applications where standard-length bits fall short. With a 135-degree split point and self-centering tip geometry, this bit starts on contact without a center punch and resists walking on curved or angled surfaces. The 2-flute spiral flute design clears chips efficiently while the web-thinned, tapered web reduces thrust requirements during drilling. At 6 inches overall length and an 11/64 inch (0.1719 inch) diameter, it suits sheet metal, structural, and aerospace-style fabrication work performed by machinists, aircraft mechanics, and metalworking tradespeople.

This bit is built for general-purpose drilling in metals and composite materials where extended reach is required. The bright, uncoated finish makes it suitable for use with cutting fluids or dry. The straight-cylindrical shank seats securely in standard drill chucks and quick-change holders. Applications include drilling through structural assemblies, stacked materials, and deep-cavity components where a shorter bit cannot maintain the required depth or clearance. It meets NAS 907 standards, reflecting dimensional and performance compliance for aircraft-grade tooling.

Key Features

• Carbide-tipped construction for extended tool life in metal and composite drilling
• 135-degree split point is self-centering and reduces the need for a center punch
• 6-inch overall length provides extended reach into deep or obstructed work areas
• Web-thinned, tapered web lowers cutting thrust and reduces heat buildup
• Right-hand spiral flute geometry promotes efficient chip evacuation
• Meets NAS 907 dimensional standards for aircraft-grade drill tooling

Compatibility

Designed as a general-purpose aircraft extension drill bit compatible with standard drill chucks and quick-change holders accepting an 11/64 inch straight-cylindrical shank. Suitable for use in portable drills, drill presses, and CNC setups running right-hand rotation.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with metal drilling operations and applicable shop safety standards. Secure the workpiece fully before drilling to prevent bit deflection or material movement. Ensure the chuck is properly tightened on the straight-cylindrical shank before operation. Use appropriate cutting fluid for the material being drilled to extend bit life and improve hole finish.
