The threaded connection column tooth bit is mainly used with hydraulic rock drill (or pneumatic rock drill) and hydraulic drill rod (air drill rod). Used in the mining of underground mines and open-pit mines.
Usually connected with MM or MF drill rods, suitable for rock drills, suitable for tunnel excavation, rock formation and underground excavation operations. It is widely used in mining engineering roadways and engineering tunnel excavation.
Threaded button bits are made of high-quality steel and cemented carbide as raw materials. After advanced heat treatment, the button bits can meet the requirements of withstanding hard rock formations, and can minimize the energy transmission process. The force of the fixed tooth is uniform and it is not easy to lose the tooth or the tooth, so that the impact energy can be concentrated on the rock to achieve the purpose of high-efficiency tunneling.
