The drill bit plays a pivotal role in the drilling process of the water well drilling rig. The quality of a drill bit directly affects the efficiency of water well drilling and the quality of the holes, so we need to pay attention to the selection and use of the drill bit. During the drilling process, the operator should pay attention to the drilling usage of the drill bit, so that the drill bit can perform better production operations. Several aspects of the drill bit in the water well drilling rig need to be paid attention to:

1. After the drill bit of the water well drilling rig drills into the structure, the center drilling tool needs to be replaced in time. First, the bottom of the hole needs to be cleaned, and then the residue at the bottom of the hole should be blown clean. The tool is slowly lifted upwards, and it is most suitable when the lifting force is just enough to lift the drilling tool.

2. The drill bits of the water well drilling rig are summarized during the drilling process. It is also necessary to carefully observe the follow-up situation of the casing, keep abreast of the specific conditions in the hole, and keep the hole clean in time when necessary. During the process, strong lifting is prohibited.

3. Sometimes there will be a lot of residual slag at the bottom of the hole of the water well drilling rig, and the rotating part of the eccentric bit will be stuck by the slag, which will affect its production. At this time, it is necessary to transport compressed air and clean the hole again , and make the down-the-hole hammer work for a short time, and then restart the lifting operation of the center drilling tool.
