DTH rock drill bits are mainly used for cutting, drilling and other hard non-ferrous materials such as marble, granite, glass, ceramics, hard concrete and brick. Different types of drill bits have suitable drill pipes.


Therefore, when using the DTH drill bit, we should pay attention to selecting the DTH drill bit according to the rock formation, ie hardness and corrosiveness. Different types of alloy teeth are suitable for drilling different rocks, and in the process of rock drilling, it is necessary to ensure the dive. The hole rig has sufficient pressure to avoid problems that occur durin
