In the drilling process, the drill bit is the main tool to break the rock, and the wellbore is formed by the drill bit breaking the rock. How well a wellbore is formed and the length of time it takes are not only related to the characteristics of the rock in the drilled formation and the performance of the drill bit itself, but also to the degree of mutual matching between the drill bit and the formation. Reasonable selection of drill bits plays an important role in increasing the drilling speed and reducing the overall cost of drilling.

The ancient blast-type mining has serious environmental damage and waste of resources. At present, the most popular mining method is diamond wire saw rope mining.

Generally speaking, the working environment of diamond saw blades is relatively harsh. Its main purpose is to saw stone, and it is widely used in the cutting of granite, marble, ceramic wall and floor tiles and concrete products. It is widely used in the stone and building materials industries, and it is a very important processing tool.

Diamond grinding wheel is a bonded abrasive tool made of diamond abrasive as raw material, metal powder, resin powder, ceramic and electroplated metal as binder.

Diamond wire saw rope is suitable for cutting reinforced concrete, stone and other materials.

Diamond beaded wire rope is a kind of saw designed to cut brittle and hard materials using the principle of wire sawing. Wire saw machines are widely used in mining granite, marble and other quarries, replacing the traditional way of construction by punching or drilling holes, greatly improving work efficiency.
