Precision Twist Drill 6001224 9/64 Inch Hss Aircraft Drill

Product Description

The PRECISION TWIST DRILL 6001224 is a high speed steel aircraft extension drill bit designed for deep-reach drilling applications in metal, composites, and structural materials. Built to Series 500-6 specifications, it features a 135-degree split point that self-centers on contact, eliminating the need for a center punch and reducing walking on curved or angled surfaces. The two-flute spiral design with web thinning and a tapered web configuration promotes efficient chip evacuation and reduces feed pressure. The oxide finish provides a degree of lubricity and corrosion resistance during cutting. Licensed trades and maintenance professionals working on airframe structures, equipment frames, and extended-reach fastener locations will find this bit suited for close-tolerance work.

This drill bit is sized at 9/64 inch (0.1406 inches decimal) with a flute length of 1.75 inches and an overall length of 6 inches, giving it the extended reach characteristic of aircraft-series tooling. It is appropriate for use in hand-held electric or pneumatic drills and drill presses in both shop and field environments. The straight cylindrical shank fits standard chucks. Right-hand cutting direction is standard. General-purpose tool performance rating makes it suitable for production and maintenance drilling across a range of base materials.

Installation Notes

Installation of this drill bit should be performed by a qualified technician or machinist familiar with metal drilling procedures. Secure the shank fully in the chuck before operation and verify chuck tightness. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable facility safety procedures and any relevant industry standards for the base material being drilled.
