Value Collection 261023 Aircraft Extension Drill Bit 23/64

Product Description

The VALUE COLLECTION 261023 is a carbide-tipped aircraft extension drill bit designed for deep-reach drilling in aerospace, structural, and industrial applications. Built to NAS 907 standards, this bit features a 135-degree split point that is self-centering and web-thinned, reducing walking and cutting effort on entry. The 23/64 inch (0.3594 inch decimal) diameter and 3.5 inch spiral flute length provide chip clearance in extended-depth bores. The bright/uncoated finish suits general-purpose use across a range of base metals. Licensed trades and industrial machinists install this type of bit where standard-length drills cannot reach the workpiece.

This drill bit is suited for aerospace maintenance, structural steel fabrication, shipbuilding, and any application requiring extended reach beyond what a jobber-length bit can deliver. The 6 inch overall length gives access to recessed or stacked-material drilling locations. Its general-purpose performance rating makes it appropriate for right-hand drilling in aluminum, mild steel, and similar materials where a carbide-tipped edge provides durability over high-speed steel alternatives.

Key Features

• Carbide-tipped cutting edge for extended service life in abrasive and harder materials
• 135-degree split point is self-centering and reduces drill walking on entry
• Web-thinned, tapered web configuration lowers thrust and improves chip flow
• Straight-cylindrical shank fits standard drill chucks without an adapter
• Two-flute spiral design clears chips efficiently during deep-reach drilling
• Meets NAS 907 standard for aircraft extension drill geometry

Compatibility

Designed as an OEM-style replacement and general-use aircraft extension drill bit for applications requiring a 23/64 inch diameter, 6 inch overall length, straight-cylindrical shank drill conforming to NAS 907.

Installation Notes

This bit is installed by machinists, aviation maintenance technicians, and structural trades using a standard drill press, magnetic drill, or hand-held drill with a compatible chuck. Secure the workpiece before drilling and use appropriate cutting fluid for the base material to manage heat at the carbide tip. Inspect the cutting edge before each use and replace if chipping is visible. Follow applicable shop safety standards and any facility-specific procedures for drilling into structural or pressurized components.
