Precision Twist Drill 6001282 Aircraft Drill Bit 0.082 in

Product Description

The PRECISION TWIST DRILL 6001282 is a high speed steel aircraft extension drill bit designed for precision drilling in metalworking and aerospace maintenance applications. Built to Series 501-6 specifications and conforming to NAS 907 Type B standards, this bit features a 135-degree split point that is self-centering for accurate starting without a center punch. The 0.082-inch diameter corresponds to wire gauge size 45, with a straight-cylindrical shank of the same diameter for secure chuck grip. The spiral flute and web-thinned, tapered web construction reduce cutting resistance and improve chip evacuation in deep-hole drilling scenarios.

This drill bit is suited for general-purpose metal drilling tasks including aircraft sheet metal work, structural repair, and precision fabrication where tight tolerances are required. The oxide finish provides a degree of surface protection and reduces friction during cutting. The 1.125-inch flute length at a 4xD ratio makes it appropriate for through-hole and moderate-depth drilling in materials typical of aerospace and light industrial environments. Installation and use are performed by machinists, aviation maintenance technicians, and metal fabricators working with drill presses, portable electric drills, or pneumatic tools.

Key Features

• 135-degree split point is self-centering, reducing the need for center punching on flat and curved metal surfaces
• Wire gauge size 45 (0.082 inches) straight-cylindrical shank for consistent chuck fit
• High speed steel construction provides durability across a range of ferrous and non-ferrous metals
• Oxide finish reduces friction and provides light corrosion resistance during storage and use
• Web-thinned, tapered web design lowers cutting torque and improves chip clearance
• Meets NAS 907 Type B standards for aircraft-grade drilling applications

Compatibility

Designed as an OEM-style replacement or standard-use drill bit for applications requiring NAS 907 Type B compliant tooling in aircraft sheet metal, precision metalworking, and general-purpose drilling operations.

Installation Notes

This drill bit is installed and used by machinists, aviation maintenance technicians, and metal fabricators. Secure the shank fully in the chuck of a drill press, hand drill, or pneumatic drill before operation, and verify that the chuck is tightened properly to prevent slippage. Use appropriate cutting fluid or lubricant when drilling harder metals to extend tool life and maintain hole quality. Follow applicable workplace safety standards and aviation maintenance manual procedures when performing aircraft structural drilling.
