Introduction To The Importance Of Top Hammer Drilling Tools

  •        For DTH Drill Pipe, the importance of the drill bit is self-evident. The quality of a drill bit directly affects the efficiency and hole quality of DTH Drill Pipe, 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 use of the drill bit to make the drill bit better for production operations. Several aspects of the drill bit in DTH Drill Pipe:

    1. After the drill bit of DTH Drill Pipe is drilled into the structure, the center drill 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 is blown clean. After the drill stops rotating, put the DTH Drill Pipe in again The drill tool is slowly lifted upwards. It is most suitable when the lifting force is just enough to lift the drill tool.  
      2. During the drilling process of the drill bit of DTH Drill Pipe, it is necessary to carefully observe the follow-up situation of the casing, timely understand the specific situation in the hole, and keep the hole clean when necessary, and the drill bit in the DTH Drill Pipe It is forbidden to pull out forcefully during the drilling process.  
             3. Sometimes the bottom of the hole of DTH Drill Pipe will leave a lot of residual slag. The rotating part of the eccentric drill bit will be blocked by the slag, which will affect its gathering production. At this time, it is necessary to deliver compressed air and carry out the hole again. Clean and make the down-the-hole hammer work for a short period of time, and then restart the lifting operation of Top Hammer Drilling Tools.
