A brief description of percussion rock drill bits.
Percussion rock drill bits are one the most popular drill tools for borehole drilling equipment in the market around the world. Percussion rock drill bits are powered by compressed air through a DTH hammer, the rocks will be hit into pieces by the percussion rock drill bits while drilling. Percussion rock drill bits are attached to the DTH hammer, and the DTH hammer is powered by compressed air and then the rock layers will be hit into pieces beneath the earth. Some will also call percussion rock drill bits a DTH hammer drill bit.
What are the features of percussion rock drill bits?
- The drilling rate of percussion rock drill bits is faster and tough.
- The cutting head of percussion rock drill bits is different according to the hardness of the rock layers, the cutting head can be Center drop / Flat/convex/concave/double gauge face bits.
- The percussion rock drill bits are made of alloy steel, and they can be high pressure, low pressure types.
- Percussion rock drill bits are used for drilling water boreholes and boreholes on the rocks.
The cutting head types of percussion rock drill bits.
- Drop center cutting head of percussion rock drill bits’ penetration rates in soft to medium hard and corrosive rock formations is high.
- The concave face of percussion rock drill bits is specifically for medium hard and homo generous rock formations.
- The convex face of percussion rock drill bits’ penetration rates in soft to medium-hard is high. It is the most wear resistance DTH hammer drill bit.
- The double Gauge Face of percussion rock drill bits is suitable for fast penetration rates in medium to hard rock formations. It is designed for high air pressures and good wear resistance.
- The flat face of percussion rock drill bits is suitable for hard to harder and abrasive rock formations.

What is the price of percussion rock drill bits?
The price of percussion rock drill bits is based on the size and depth of the water borehole. Usually, the following information needs to be collected. What is the diameter of percussion rock drill bits? What is the air pressure? And the types of cutting head is very important too. Compared with water borehole drilling equipment, it is cheap.
