1. Matrix type PDC drill
Matrix-type diamond compact (PDC) drill is a cutting-type drill in which the diamond compact is welded to the drill matrix by brazing. The matrix drill bit is sintered with tungsten carbide powder, brazed on the tungsten carbide matrix with artificial polycrystalline diamond composite sheet, and used natural diamond to keep the diameter.
2. Steel body PDC drill
Steel body PDC bits are machined from nickel, chromium and molybdenum alloys. After heat treatment, drill holes on the drill bit body, press the synthetic polycrystalline diamond composite sheet into (tight fit) the drill bit body, and use columnar tungsten carbide to maintain the diameter.
