1. Diamond
A cutting tool that uses a diamond material as a cutting edge is a diamond mining drill. The main advantage of the diamond mining bit is that it can adapt to highly abrasive and hard geological structures, and its cutting performance is relatively good. It has very important advantages in high-speed drilling.
The polycrystalline diamond composite mining drill bit is mainly composed of four parts, namely, the diamond composite wafer, the nozzle, the matrix and the drill body. Ordinary diamond drill has four main components, namely diamond particles, nozzle, nozzle body and drill body. Due to the excellent cutting performance of diamond drill bits, when choosing a diamond drill bit as a coal drilling tool, it can drill at high speed and expand the drilling depth to a certain extent. In the process of using diamond drills for coal drilling, you need to pay attention to the following aspects:
First of all, the price of diamond drills is relatively high, so they should be handled carefully during use to reduce the degree of damage;
Secondly, diamond mining drill bits have certain defects in thermal stability, so the cooling performance and cleaning conditions of the drill bits must be ensured during use.
Third, its texture is relatively brittle, so the impact resistance of diamond drills is very poor. Strictly perform strict and standardized operations in strict accordance with the relevant regulations of diamond drilling rigs.
2. Cone btis(tricone bits)
According to the structure of the cone drill(tricone bits), it can be divided into five parts: water eye, bearing, palm, cone and drill body. The thread is usually on the upper part of the roller cone bit, and the drill string and the thread are connected to each other. The lower part of the drill will have a tapered roller with three palms on it. The roller will break the rock with its own cutting teeth. The passage of the drilling fluid is the water eye of the drill bit.
