Type F Cobalt Screw Machine Length Aircraft Drills - Letter
These letter size type "F" screw machine length drills made from heat resistant cobalt steel are heavy duty construction for drilling high temperature and high strength alloys. They are furnished with a 135 degree split point to NAS specifications. Treated with a bronze oxide for wear resistance and identification.
- High red hardness and abrasion resistant
- Heavy-duty construction provides greater strength and rigidity
- Designed for drilling tough and abrasive materials, high temperature alloys, stainless and heat-treated high-strength steels
These drills are designed for drilling holes in hard, tough materials such as stainless steel, titanium and other high strength alloys. The special P3 split point and wear resistant surface treatment on these cobalt aircraft style drills will provide long life in power feed or portable applications. The short stubby length is suitable for drilling aircraft bodies and other tough thin wall materials.
