Value Collection 01008085 Aircraft Extension Drill Bit

Product Description

The VALUE COLLECTION 01008085 is a wire gauge size 8 aircraft extension drill bit designed for reaching into deep or recessed workpieces where a standard-length bit cannot access. Manufactured from high-speed steel with an oxide finish, the bit features a 135-degree split point that is self-centering and reduces the need for a center punch on most surfaces. The 6-inch overall length and 2.4375-inch spiral flute provide extended reach without sacrificing chip evacuation performance. This bit is suited for general-purpose drilling in metal, plastic, and composite materials and is typically used by maintenance technicians, aviation mechanics, and fabricators.

Aircraft extension drill bits are used in applications where access depth exceeds the reach of jobber-length bits. Common scenarios include drilling through structural panels, bulkheads, frames, and assemblies where the drill chuck must remain outside the work envelope. The right-hand cutting direction and two-flute spiral geometry support consistent chip removal in through-hole and blind-hole drilling operations. The straight cylindrical shank is compatible with standard three-jaw drill chucks and quick-change adapters.

Key Features

• Wire gauge size 8 (0.1990 inches decimal) for precise hole sizing
• 135-degree split point with self-centering geometry reduces walking and eliminates center-punching on most surfaces
• High-speed steel construction with oxide finish for corrosion resistance and lubricity
• 6-inch overall length provides extended reach into deep or confined work areas
• Web-thinned, tapered web configuration reduces cutting resistance and improves chip flow
• Two-flute right-hand spiral design supports efficient chip evacuation in metal and composite materials

Compatibility

Designed as an OEM-style general-purpose aircraft extension drill bit compatible with standard three-jaw drill chucks and quick-change chuck systems accepting a 0.1990-inch straight cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified technicians familiar with metalworking or aircraft maintenance practices. Secure the workpiece before drilling and confirm the chuck is fully tightened on the straight shank to prevent slipping. Use appropriate cutting fluid when drilling ferrous metals to extend tool life and improve hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
