There are also many types of drilling bits for a drilling machine, different types of drilling bits have different applications. DTH drilling bits and Rotary tricone drilling bits are the most preferable drilling bits when it comes to drilling a water well. One is working with a screw air compressor and the other is working with a mud pump.
DTH drilling bits are very efficient when drilling through a rock formation under the ground, it works like a pneumatic hammer that hits the rock into pieces while drilling a water borehole. The screw air compressor sends the compressed air to the DTH drilling bits as power sources of percussion. The rotation of DTH drilling bits makes the drilling process more powerful and faster.
Rotary tricone drilling bits are very suitable for drilling earth and soft rocks, but it is not that fast compared to DTH drilling bits. It drills slow and it must be working with a mud pump. The mud pump injects the water into the drilling hole and the water will cool down the heat of the rotary tricone drilling bits that are produced when drilling a borehole.
When you are going to buy drilling bits, you have to find out which one suits you most. The geological study is very important too. If you are not very clear about it, find a professional water well driller nearby and let the water well driller advise you. Or you can consult us before making the buying decision.
