Ball tooth drill head series passivation long life cycle, it does not wear life is about the same diameter drill bit grinding edge titles times 5-6 times lifetime, help save the auxiliary work, reduce workers' physical and accelerate project speed. So different diameters taper connection and threaded ball Button Bits are widely used in various types of brittle rock drill with drill car. Sweden's engineering and technical personnel believe that the ball tooth bit and hydraulic rock drills combine the best supporting modern drilling technology. The past 20 years, domestic ball tooth series drill head has developed rapidly, it is accompanied with hydraulic rock drill machine assisted rapid perforation save hours of work to improve the industry and achieve the goal of ROP. Threaded coupling stud teeth mainly hydraulic rock drill (or pneumatic drills) and hydraulic drill rod (pneumatic drill rod) supporting the use of a drill, thread through different forms of cooperation with the drill rod, puncturing operations, drill diameter by ￠ 32- ￠ 203mm, mainly used in mining underground mines, mining open pit mine and mill blast furnace openings in areas such as speed, convenience grinding Specifications: Includes a diameter of 32mm, 34mm, 36mm, 40mm, 50mm, 55mm , 60mm, 64mm, 76mm, 89mm, 102mm, 115mm and so the ball tooth bit, in addition, we can also be customized according to customer specific needs of a variety of products.
