Milwaukee® aircraft length black oxide drill bits are ideal for extra reach and deep drilling applications in metal, wood and PVC. The 135 deg split point tip delivers a precision start and prevents walking for fast, accurate holes. The 3-flat Secure-Grip™ shank holds the bit firmly in the drill chuck to prevent slipping.
