Outrigger down the hole drill

CHQ(70/70D/100/100D)

Watch
Pneumatic Drilling Rigs

Product features: CHQ down the hole drilling machine is a new type of high efficiency, semi mechanized drilling equipment. It has simple structure, small volume and light weight. It is widely used in open-pit and underground mining and engineering, such as drilling blasting holes and anchor holes, convenient and flexible. Electric power is used as power for down the hole drilling machine, with low noise and strong power. The drilling speed is 3-8 times of that of the general rock drill. The ore drilled can live with high drilling humidity within the range of Proctor hardness coefficient f = 8-16, and the drilling depth per hour is about 8-16m.
