The DTH drilling rig adopts an excellent motor, which has the characteristics of high efficiency, convenient operation, low investment and high economic benefit. Widely used in slope support, quarry, water conservancy projects, anchor bolts, highway and railway construction.
The principal drilling methods used in mines today are mechanical ones in which a drill drives cutting tools into rock by means of static or dynamic force. Percussion rock drills are the most commonly used equipment for drilling in small-scale surface or underground mining situations, whereas rotary crushing drills or down the hole drills (DTHs) are generally employed for mining in large-scale surface mines.

Face shape Features
1. Capable of drilling straighter holes in medium to hard rock which is broken or less consolidated
2. Offers high penetration rate in the above stated rock conditions
3. Has excellent air flushing characteristics
4. Predominant face style for majority of drilling conditions
1. Have a superior performance in hard, abrasive and broken rock conditions
2. They however have a slower penetration rate in comparison to a concave face bit
1. This face has been designed to offer high penetration rate in soft rock such as shale, limestone etc
2. They are recognized for having excellent capability for drilling into moderately consolidated rock conditions
At present, DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering
.Among all the drilling method, Down The Hole(DTH) drilling is being used more and more widely and has very high efficiency for some cases.
