XQZ 178
The down-the-hole drill is a medium-sized integrated down-the-hole drill developed mainly for various types of mines such as quarries, cement mines, open-pit coal mines, etc. It can complete the drilling construction of main blasting holes and pre-splitting holes. The down-the-hole drill has the characteristics of large drilling diameter, high drilling efficiency, and wide adaptability. It is widely used in the production of building materials, coal, metallurgy, chemical industry and other mines. It is also the main equipment in the construction of engineering departments such as geology, construction, hydropower, transportation and military.
