1. Face convex type: This kind of drill bit is divided into two types, single boss and double boss end face, the latter is mainly used for drill bit with larger diameter. The end face convex type DTH drill bit can maintain a high rock drilling rate when drilling hard and hard abrasive rock, but the straightness of the drilling hole is poor, and it is not suitable for rock drilling with high blast hole flatness. engineering.
2, end face flat type: This shape of the drill bit is more durable, suitable for drilling hard and extremely hard rock, but also suitable for drilling medium and hard rock and soft rock with low flatness.
3. Concave face type: This shape has a conical concave part on the end face of the bit. It is a bit of nucleation during the rock drilling process to maintain the centering performance of the drill bit. The drill hole has a good straight line. Degree, this drill bit has good drainage effect and fast drilling speed. It is a dTH drill bit that is used more on the market.
4. End face deep concave center type: The drill bit of this shape is evolved from the same type of ball tooth bit, and the center end of the end face of the drill bit has a deep concave central portion. It is used for nucleation during rock drilling and ensures the straightness of the blasthole when drilling deep holes. It is only suitable for drilling soft rock and medium hard rock.
