What is the working principle of diamond core bits? The drill bit that makes the cutting edge is called a diamond core bit. The drill bit is an integrated drill bit. The entire drill bit has no moving parts. The structure is relatively simple, with high strength, high wear resistance and impact resi
What kinds of drill pipe can be divided into? The drill pipe is a steel pipe with thread on the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device located at the bottom end of the drilling well. The purpose of t
