Made from premium High Speed steel, the drill bits are suitable for drilling many different materials including steels, aluminum and stainless steel, and have a steam oxide finish which prevents workpiece material from sticking to the cutting surfaces of the tool, so you get a clean and accurate result.

The 135 degree split point helps with self-centering and reduces the push force needed.

501-12 aircraft extension drills have a long overall length (12”) with a short flute which is especially recommended for stable drilling in areas which are hard to reach.
