This high quality auger bit may become one of your most popular drill bits. Fabricated by Freeform using advanced manufacturing techniques, this bit includes an integral lead screw with course threads for precise drilling. The lead screw minimizes bit drift or "walk" and will help "pull" the bit through wood, taking less effort by the installer. The bit is made of a heat treated, high quality carbon steel for strength and is formed having wide flutes to carry drill debris and chippings away from the bit head to reduce clogging.
