KQG100 is a kind of down-the-hole drill working with higher air pressure; it is widely used in open-pit mining and all kinds of engineering projects. It can drill pre-split hole for precise-control blasting at any angle you need, even horizontal hole close to the ground.Drilling speed is faster 8-10 times than normal drill. Drill the hole at the speed of 20-30m per hour with the rock rigidity f=6-20.
