Electric down the hole drill efficient and fast rock drill

  1、 Product introduction qk-70 electric down the hole drill is a new type of high-efficiency and widely applicable rock drilling equipment newly developed by our company
It is widely applicable to small and medium-sized mines, transportation, water conservancy, stonework and other projects, especially to the bumpy and rugged terrain where other drill trucks cannot operate normally
The machine has the advantages of simple structure, convenient operation, low price and energy saving
At the same time, it also has the function of drilling vertical and horizontal blasting holes
In particular, the machine has a low center of gravity and good detachability, which is very convenient for relocation and transportation
