HSS Aircraft Extension Drill Bit Size: 1/16″ x 12″
- The 135 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. Manufactured to aerospace standard 907.
