The PRECISION TWIST DRILL 6001155 is a high speed steel aircraft extension drill bit designed for drilling through metal in aerospace and general industrial applications. It features a 135-degree split point with web thinning for self-centering starts without a center punch, reducing walking on curved or hard surfaces. The oxide finish provides light corrosion resistance and reduces friction during cutting. At 15/32 inch (0.4688 inches) diameter with a 4-5/16 inch flute length and 6-inch overall length, this bit suits extended-reach drilling where a standard-length bit cannot access the work. Licensed HVAC, millwright, and sheet metal technicians working with structural components and ductwork will find this a reliable general-purpose cutting tool.
The 6001155 is built for applications requiring reach beyond what a jobber-length bit provides. The extended flute length allows chip evacuation in deeper holes. The straight cylindrical shank seats in standard drill chucks without modification. It is suited for right-hand drilling in ferrous metals, aluminum, and structural materials in both shop and field settings. Series 500-6 designates this as an aircraft-style extension drill, meeting NAS 907 Type B standards.
Designed as an OEM-style replacement or standard supply for any application requiring a 15/32 inch diameter, 6-inch overall length, straight-shank high speed steel extension drill bit meeting NAS 907 Type B specifications.
Installation requires a drill press, hand drill, or right-angle drill with a chuck rated for the 15/32 inch shank diameter. Secure the workpiece firmly before drilling and use appropriate cutting fluid on ferrous metals to extend bit life and maintain cut quality. Always wear eye protection when drilling metal. Inspect the bit for chipping or wear before each use; a damaged split point will reduce centering accuracy and increase the risk of bit breakage.
