Precision Twist Drill 6001465 Aircraft Extension Drill

Product Description

The PRECISION TWIST DRILL 6001465 is a high speed steel aircraft extension drill bit designed for drilling in aerospace, sheet metal, and general fabrication 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 and web-thinned for fast, accurate starts without a center punch. The straight cylindrical shank measures 0.18 inches in diameter, matching the 0.18-inch cutting diameter (Wire Size 15), and the spiral flute length runs 2.1875 inches. The oxide finish provides basic surface protection and reduces friction during cutting. This drill is installed by aircraft maintenance technicians, sheet metal workers, and general machinists.

The 6001465 is suited for through-hole drilling in aluminum, mild steel, and similar materials in both production and field repair settings. The 6-inch overall length gives extra reach for drilling in recessed areas or through stacked material where a standard-length bit cannot access. The right-hand cutting direction and two-flute spiral configuration promote efficient chip evacuation during extended drilling passes. General-purpose tool performance makes it appropriate for a wide range of shop and field tasks.

Key Features

• 135-degree split point is self-centering and reduces walking on entry
• Web-thinned, tapered web configuration lowers thrust and improves chip flow
• 6-inch overall length provides extended reach into recessed or stacked workpieces
• High speed steel construction handles a broad range of ferrous and non-ferrous materials
• Oxide finish reduces friction and surface galling during drilling
• Conforms to NAS 907 Type B standard for aerospace drill geometry

Compatibility

Designed as an OEM-style replacement or direct substitute for Wire Size 15 aircraft extension drill bits conforming to NAS 907 Type B geometry in Series 501-6 applications.

Installation Notes

Installation is performed by machinists, aircraft maintenance technicians, or sheet metal fabricators using a standard drill press, hand drill, or pneumatic drill motor with a compatible chuck accepting a 0.18-inch straight cylindrical shank. Secure the workpiece firmly before drilling and use appropriate cutting fluid for the material being drilled to maximize bit life. Inspect the cutting edges and split point for wear or chipping before each use and replace the bit if damage is observed.
