U.S.AHDD Rock Reamer with Replaceable Roller Cutters
Product Description
The reamer includes a drill pipe, a reamer bracket, a cone and a mud injection hole. The reamer bracket is fixedly connected to the drill pipe. The drill pipe is hollow and there are three cones, which are fixed on the reamer bracket through a threaded connection array. The ends of the three mud injection holes are all connected with the drill pipe, and the other end points to the cone below it, and the mud injection hole is arranged between two adjacent cones. Since the mud injection hole is directed to the cone, the mud is sprayed from the mud injection hole to the cone, which can effectively wash off the drill cuttings on the cone, prevent the cone from being blocked, improve work efficiency, and make the cone have a longer service life.
