water well 17.5inch / 445mm steel tooth bit

water well drilling 17.5inch / 445mm steel tooth bit:The gear design adopts advanced step gear structure, which realizes the permanent contact area of the single gear bit and the continuous wear of the rotating contact area. On the tooth surface of the gear, it adapts to different tooth movement cutting modes of different parts of the single gear, and the permanent contact area is distributed. In the cone, the wedge contact zone is arranged in the changing contact zone to improve the efficiency of the gravel.
