The cross drill bit belongs to the wind drill bit, because the cutter head is designed as a cross type. It is mainly used for drilling blastholes, and can drill rock holes, coal holes, concrete holes, etc.; it is used together with B22, B25 wind drill rods and rock drills. Widely used in coal fields, tunnels, metallurgy, geology, water conservancy, construction, energy. It is mainly used for drilling blastholes; it is conducive to saving auxiliary working hours, reducing workers' manual labor and speeding up the project.

 Features: The cross bit has a high wear resistance, which is five or six times stronger than the cutter head of the same diameter. Moreover, it will not break during the drilling process. Some drill bits are too poor due to the quality of the alloy blade of the cutter head. Some drills are directly stuck in the drilling work of one or two meters, and the broken bits are not easy to take out. The construction speed is directly affected.
