Down-the-hole drill is a drilling equipment widely used in construction, mining, tunneling and other projects. Its main feature is that it drives the drill bit to drill holes through compressed air, which has the advantages of high efficiency, low noise and environmental protection.
Small down-the-hole drill rigs: small giants for efficient rock drilling
Small in size and light in weight, this mini dth drilling machine is suitable for places where large and medium-sized drilling rigs cannot operate. It is convenient and flexible. The down-the-hole drill uses electric energy as power, with low noise and strong power. The drilling speed is 3-8 times that of a general rock drill, the rock hardness reaches 9, and the drilling depth per hour is 8-16 meters.
