Jobber Length Aircraft Drills
Types A, B, which are HSS and J and D cobalt jobber length drills made to NAS 907 specifications are designed specifically to drill materials used in the aircraft and aerospace industries. Split point style drills are used for easy starting in a variety of space age materials.
Recommended by the National Aircraft Standards Committee which designed them as NAS-907 Type A drills. Furnished with 118 degree split point and bright finish.
The difficult drilling of aerospace parts is handled by the design of these heavy duty drills. Made to NAS Type B specifications for drilling difficult materials.
These Type D drills made from heat resistant cobalt steel are heavy duty construction for drilling high temperature and high strength alloys. Favored for the toughest jobs.
Type J drills made from heat resistant cobalt steel. Heavy duty construction for drilling high temperature and high strength alloys. 135 degree split point; manufactured to NAS specifications.
