why our brazed diamond drill

why our brazed diamond drill bit hole saw works more efficiency in high-temperature and low-temperature evironment

     Keeping the drill bit cool is big problem for hole saw, specially when it works on hard material like marble, stone and tile. The normal way is using water to cooling, or even need to stop work until it is cool. 

        We have our way to solve this problem. We improved our technology of drill bit hole saw to make it works more smoothly even in high-temperature and low-temperature evironment. 

      Our drill bit hole is filled with wax. the melting point and freezing point of wax are both low. So when the evironment temperature is high, the  wax is melted to help the drill bit cool. When the evironment tempertaure is low, the wax is freezed to help the drill bit hot. This makes work more efficiency.
