diamond core drill bit for granite Blind Road Stone

In the construction of modern cities, the roads of all major, small and medium-sized cities are paved with blind roads to help the blind people walk. The strip bulge indicates that the execution is unimpeded, and the circular bulge marks need to stop, turn, etc.

The stone commonly used for paving is wear-resistant and high hardness granite. The diamond bit designed and produced by our company is specially designed for this purpose and has the characteristics of long service life, wear resistance and sharpness.

At the same time, this drill bit can also be used to clean the bottom of stone products. For example, a flowerpot made of pebbles needs a drill bit to remove the excess stone at the bottom.
