The High speed diamond bur is a consumables appliance for dentists. It is a very thin steel needle. The needle consists of a needle and a needle handle. It can be inserted into a high-speed and low-speed mobile phones to help dentists open their teeth and repair teeth.
The burs are currently divided into tungsten steel bur and diamond bur. Among them, the use of tungsten steel burs is more common in foreign countries, and domestic and dentists mainly use diamond burs.
Emery wheel bur heads have small diamond grains attached to the outer periphery of the drill head. These corundum grains have undergone despeckling, demagnetization, spheronization, and purification, and have been excellent in sharpness and wear resistance. Emery burs will drop gradually during use, and usually the life of the bur will end when the emery drops half.
