In order to ensure drill bit life, drilling must ensure that the drill is fully cooled, before drilling, fully open the cooling water, stop drilling after cooling water, the higher the drilling speed, the greater the water demand.
Diamond engineering thin-wall drill bit adopts advanced sintering process with high performance price ratio. Drilling speed, high efficiency. It is recommended to use fixed drilling rig or hand drilling rig. Widely used in building, water, electricity, gas, heating, air conditioning, pipe installation hole hit the wall. Drilling, cutting and coring of expressway, airport runway, bridge and tunnel. Drilling of non-metallic hard and brittle materials such as stone, ceramics, etc..
This kind of drill is specially drilled on reinforced concrete.
It is mainly a cement made to punch in front of it is made of carborundum,
