Precision Twist Drill 6001316 Letter P Hss Aircraft Drill

Product Description

The PRECISION TWIST DRILL 6001316 is a Letter P, high speed steel aircraft extension drill bit designed for deep-hole drilling applications in metal fabrication, aerospace, and maintenance environments. The bit features a 135-degree split point with web thinning for self-centering entry without a center punch. At 0.323 inches in diameter and 3.3125 inches of flute length, this Series 502-6 drill delivers extended reach beyond a standard jobber bit. The straight-cylindrical shank seats securely in standard drill chucks. An oxide finish provides basic lubricity and mild corrosion resistance during use. Licensed machinists, aviation maintenance technicians, and industrial tradespeople are the primary installers.

This drill bit is suited for through-hole and clearance-hole drilling in ferrous and non-ferrous metals where extended flute length is required to reach recessed or deep workpiece features. The 4xD flute-length-to-diameter ratio gives it the reach needed for aircraft skin, structural members, and similar assemblies. The right-hand spiral flute geometry promotes chip evacuation in deep cuts. It complies with NAS 907 Type B standards, making it appropriate for aerospace and defense maintenance work where specification compliance is required.

Key Features

Compatibility

Designed as an OEM-style aircraft extension drill bit compatible with standard drill chucks accepting a 0.323-inch straight-cylindrical shank. Conforms to NAS 907 Type B specifications.

Installation Notes

Installation is performed by machinists, aviation maintenance technicians, or qualified metalworkers using standard drill presses, magnetic drills, or handheld power drills. Secure the straight-cylindrical shank firmly in the chuck before operation and verify the workpiece is clamped to prevent movement. Use appropriate cutting fluid for the material being drilled to extend tool life and improve hole finish. Follow applicable workplace safety standards and equipment manufacturer guidelines when operating rotary cutting tools.
