Value Collection 261019 Aircraft Extension Drill 19/64 in

Product Description

The VALUE COLLECTION 261019 is a carbide-tipped aircraft extension drill bit designed for deep-reach drilling applications in metal, composites, and structural materials. Built to Series 2610 standards and compliant with NAS 907, this bit features a 135-degree split point for self-centering entry without a center punch, reducing walking and improving hole accuracy. The 19/64 inch (0.2969 inch decimal) diameter and 3-1/16 inch flute length make it well suited for accessing recessed or hard-to-reach areas on aircraft structures, machinery frames, and fabricated assemblies. Installed by aviation maintenance technicians, structural fabricators, and industrial machinists, this bit is a reliable general-purpose tool for precision drilling in production and field repair environments.

This aircraft extension drill is intended for use in deep-hole drilling scenarios where a standard-length bit cannot reach the workpiece. The extended overall length of 6 inches allows clearance around obstructions typical in airframe panels, structural steel assemblies, and heavy equipment frames. The straight-cylindrical shank accepts standard drill chucks without adapters, making it compatible with common corded and pneumatic drill drives used in industrial and MRO settings. The right-hand cutting direction and two-flute spiral configuration support efficient chip evacuation during through-hole drilling in ferrous and non-ferrous metals.

Key Features

• Carbide-tipped construction for extended wear life in hard and abrasive materials
• 135-degree split point is self-centering and eliminates the need for a center punch
• Web-thinned tapered web reduces thrust force and improves cutting efficiency
• 6 inch overall length provides reach into deep or obstructed workpiece locations
• Straight-cylindrical shank fits standard drill chucks without special adapters
• NAS 907 compliant for use in aerospace and aviation maintenance applications

Compatibility

Designed as an OEM-style general-purpose aircraft extension drill bit suitable for use with standard drill chucks in corded electric, pneumatic, and magnetic drill press setups across industrial, aerospace maintenance, and fabrication applications.

Installation Notes

This drill bit is typically installed and operated by machinists, aviation maintenance technicians, or structural fabricators using standard drill chucks and appropriate drill drives. Secure the workpiece firmly before drilling and verify chuck engagement before operation. Use appropriate cutting fluid or coolant for ferrous metals to preserve carbide tip life. Inspect the cutting edges for chipping or wear before each use and replace the bit if tip damage is observed.
