Precision Twist Drill 6001305 No. 35 Hss Aircraft Drill

Product Description

The PRECISION TWIST DRILL 6001305 is a No. 35 wire-size aircraft extension drill bit designed for drilling in deep or hard-to-reach locations where standard-length bits fall short. Manufactured from high speed steel with an oxide finish, the bit features a 135-degree split point that is self-centering and web-thinned for reduced thrust and cleaner entry without a center punch. The overall length of 6 inches combined with a 1.5-inch spiral flute makes this bit well suited for aircraft-style drilling applications requiring extended reach and consistent hole quality. It is installed and used by aviation maintenance technicians, machinists, and precision sheet-metal tradespeople.

This bit is appropriate for general-purpose drilling in metal, including steel and aluminum, where a standard jobber-length bit cannot access the work area. The 6-inch overall length provides the extension needed for structural and panel drilling in tight assemblies. The right-hand cutting direction and two-flute spiral configuration promote efficient chip evacuation during extended-reach drilling operations. It conforms to NAS 907 Type B standards, making it suitable for use in aerospace and precision manufacturing environments.

Key Features

• No. 35 wire size (0.110 inches diameter) straight-cylindrical shank for secure chuck engagement
• 135-degree split point is self-centering and eliminates the need for a center punch on most materials
• Web-thinned, tapered-web construction reduces cutting resistance and drill walk
• High speed steel construction provides heat resistance for metal drilling applications
• Oxide finish improves lubricity and corrosion resistance during use
• NAS 907 Type B compliant for aerospace and precision manufacturing standards

Compatibility

Designed as a general-purpose aircraft extension drill bit compatible with standard 3-jaw drill chucks and collets accepting a 0.110-inch straight-cylindrical shank. Conforms to NAS 907 Type B specifications.

Installation Notes

This bit is typically used by machinists, aviation maintenance technicians, and precision metalworkers. Secure the shank fully in a drill chuck before operation and verify chuck tightness before starting the spindle. Use cutting fluid appropriate for the workpiece material to extend bit life and improve hole finish. Inspect the cutting edges for wear or chipping before each use, as a damaged split point on a small-diameter bit can cause breakage under load.
