Product Overview
HSS Aircraft Extension Drill Bit are manufactured to Aerospace Standard 907. The 135 Degree Degree split point is self-centering and reduces thrust. Ideal for drilling in mild steel where extra length for reach is required. They have a black oxide surface treatment that is abrasion resistant, reduces chip welding and improves chip flow. Sizes smaller than 1/16" have the 118 Degree standard point.
