Aircraft maintenance drill bit meets NAS 907 Rev. 14 and ANSI standards * Cobalt steel provides extended tool life compared to high-speed steel drill bits when drilling hard materials * Uncoated (bright) finish is an untreated surface that can be used on a range of materials * Self-centering 135-degree split point penetrates hard material without a pilot hole and produces small chips to reduce clogging * Short flutes and extended length allow accurate drilling in hard-to-reach areas
