Precision Twist Drill 6001293 Aircraft Extension Drill Bit

Product Description

The PRECISION TWIST DRILL 6001293 is a wire gauge size 48 aircraft extension drill bit designed for precision drilling in tight or deep-reach applications. Built from high speed steel with an oxide finish, it features a 135-degree split point that is self-centering, reducing the need for a center punch and minimizing walking on entry. The bit has a 0.076 inch decimal diameter, a 1 inch flute length, and an overall length of 6 inches. The straight-cylindrical shank matches the decimal diameter at 0.076 inches. This is a general-purpose drill suited for use by aviation maintenance technicians, machinists, and mechanical contractors working with metal substrates.

This bit is purpose-built for aircraft and aerospace drilling applications where extended reach is required. The 6 inch overall length allows access to recessed or structural members where a standard-length bit cannot reach. The spiral flute geometry with a tapered web configuration and web-thinned point promotes chip evacuation and reduces thrust load. It is appropriate for use in ferrous and non-ferrous metals in both production and maintenance environments. The right-hand cutting direction is compatible with standard corded and cordless drill drivers and drill presses.

Key Features

• Wire gauge size 48 (0.076 inch decimal diameter) for precision small-hole drilling
• 135-degree split point with self-centering geometry eliminates center punch in most applications
• High speed steel construction with oxide finish for corrosion resistance and lubricity
• 6 inch overall length for extended reach into confined or structural areas
• Web-thinned, tapered web configuration reduces cutting resistance and thrust
• Meets NAS 907 Type B standards for aircraft drilling applications

Compatibility

Designed as an OEM-style replacement or standard-fit drill bit for use in 0.076 inch diameter applications conforming to NAS 907 Type B specifications, compatible with standard straight-shank drill chucks accepting bits at or above 0.076 inch shank diameter.

Installation Notes

Installation is performed by machinists, aviation maintenance technicians, or mechanical tradespeople using a drill press, hand drill, or drill motor with a compatible chuck. Always power down and secure the drill before changing bits. Use appropriate cutting fluid for the workpiece material to extend bit life and improve hole quality. Follow applicable workplace safety standards and aviation maintenance manuals when drilling structural components.
