High-quality Reaming Bit can generally meet various geological conditions. As long as they are drillers and can strictly follow various construction processes, they can ensure that in long-term operation, they can still ensure that the performance remains unchanged. The design plan of the reaming drill bit is to use three cones and a pyramidal pyramid structure to achieve the effect of crushing stone particles and cutting rocks through rows and rows of inlaid steel teeth.When replacing a new reaming bit, it needs to run in with the drilling for a period of time, when it reaches a distance of more than one meter from the bottom of the hole, start stable pressurization to drill, and immediately after the drill and skip drilling If there is a reaction, eliminate the fault. If the drilling depth is shallow, you can start drilling immediately to observe whether the drill bit is damaged.In the process of using the reaming bit, increase the water flow as much as possible. The higher the pressure of the water flow, it can ensure the effect of breaking the rock. At the same time, it can bring out some small stones, which can reduce the reaming bit Drilling resistance to improve the efficiency of drilling.
