The advantage of this kind of drill bit is that the blast hole is easy to open the door, it is difficult to get stuck, the blasthole is round, the drilling speed is high, and the amount of coarse grain cuttings is increased, the specific work of the crushing is low, and the dust concentration of the working surface is low, hard. The consumption of the alloy is also less, and the grinding cost is also lower, but the diameter of the hole in the well should not be less than 40mm. Such drills are increasingly being used on site due to their unique advantages.
