DM70Y down gole frill with simple structure and lighter weight lower air pressure, could work easily at limited sites. Equipped hydraulic power will provide stronger power and less noise. The drilling speed is as 3-8 times as common low air pressure DTH drill.
Drill the hole at the speed of 8-16km/h with the rock rigidity f=6-20. The dril is equipped with crawler unit, it's good for the small mining areas in the productivities of 200,000m3 annually, or serves as the auxiliary equipment of the large or medium mining to drill the side hole
