DRILLING WITH DOUBLE LIFETIME

The Fractional Double-Ended Black Oxide Drill Bit delivers double the drilling lifetime. The bit is usable at both ends due to two drill bit tips and flutes. It is ideally suited for assembly work, car body work and metal machining. It can also be used for drilling rivets or thread holes in thin-walled materials. Use this bit when drilling non-ferrous metal, sheet steel and plastics.
