502-6 Aircraft extension drill bits conform to NAS907 type B standard and have a long overall length (6”) with short flutes, recommended for stable drilling in hard to reach areas.
The drills have a 135 degree split point which helps with self-centering when used by hand – no more wandering all over the workpiece – and reduces the push force required.
Manufactured from premium High Speed Steel (HSS), the drill bits can be used in many materials including aluminum, steels and stainless steel and have a steam oxide finish which ensures a more accurate and cleaner hole by preventing workpiece material from sticking to the cutting surfaces of the tool.
502-6 aircraft extension drill bits are available in a range of letter sizes from A to Z.
