KQG**0Y high air-pressure down-the-hole drill uses a diesel engine (or electric motor) to drive the hydraulic oil pump to provide power for the moving, turning, propelling and lifting of the hydraulic motor of the drill as well as swing angle positioning. When it works, only the down-the-hole hammer consumes the compressed air. Compared to full air-operated drills, it can save up to ****0% energy (fuel oil or electric energy). It is mainly used in drilling work, for example, surface mining, hydroelectric engineering, road construction and rock excavation. Specification table for KQG**0Y high air-pressure down-the-hole drill
