Vacuum Brazed Diamond core Drill Bits A

Diamond drill bits including our Monolayer Vacuum Brazed  Diamond Drill Bits and Multilayer Vacuum Brazed of Diamond Drill Bits are the best tools for drilling the hard brittle materials such as stone, glass and ceramics. To protect the drill bit wall worn out in drilling processes, we brazed several diamond strips on the outside surface, this drill bit called Brazed Wall Drill Bit.  Another kind of drill bit called Drum Grinder Drills Bit, which entire outside wall is brazed of diamond, thus the drill bit not only can be used for drilling hole but also used for grinding like a drum grinder.
