Chicago-latrobe 11010 Aircraft Extension Drill 13/64 in

Product Description

The CHICAGO-LATROBE 11010 is a high speed steel aircraft extension drill bit designed for precision drilling in aerospace and industrial applications. Built to Series 906 standards, this bit features a 135-degree split point for self-centering entry without a center punch, reducing walking and improving hole accuracy. The extended overall length of 6 inches allows access to recessed or hard-to-reach workpieces. With a 13/64 inch (0.2031 inch) diameter and a right-hand spiral flute, it is suited for a wide range of ferrous and non-ferrous materials in both shop and field environments.

This drill bit is used in aerospace, sheet metal, automotive, and general manufacturing applications where extended reach and precise hole placement are required. The aircraft extension length makes it particularly useful when standard-length bits cannot access the drilling location. It is installed by machinists, maintenance technicians, sheet metal workers, and other trade professionals working with drill presses, hand drills, or right-angle drill motors. The oxide finish provides light corrosion resistance and reduces chip welding during drilling operations.

Key Features

• 135-degree split point for self-centering, walk-free entry
• Aircraft extension length — 6 inches overall — for deep or restricted-access drilling
• High speed steel construction for general-purpose ferrous and non-ferrous drilling
• Straight-cylindrical shank compatible with standard drill chucks
• Web-thinned tapered web reduces thrust and improves chip evacuation
• Oxide finish for light corrosion resistance and reduced friction
• Meets NAS 907 Type B standards

Compatibility

Designed as an OEM-style replacement and standard tooling option for use in any drill press, hand drill, or right-angle drill motor accepting a straight-cylindrical shank with a 13/64 inch diameter, conforming to NAS 907 Type B specification.

Installation Notes

Install this bit into a compatible drill chuck and tighten securely before operation. Ensure the workpiece is properly fixtured or clamped to prevent movement during drilling. Use appropriate cutting fluid or lubricant when drilling harder materials to extend bit life and maintain hole tolerance. Inspect the split point and cutting edges for wear before each use, and replace the bit if chipping or dulling is observed.
