Product Description
OUr carbide burs are made of tungsten carbide, a metal that is extremely hard (about three times stiffer than steel) and can withstand high temperatures. Because of their hardness, carbide burs can maintain a sharp cutting edge and be used many times without becoming dull. However, carbide burs are brittle and have a tendency to fracture under pressure. They are best operated at high speeds with light pressure.
Carbide burs are used most commonly for excavating and preparing cavities, finishing cavity walls, finishing restoration surfaces, drilling old fillings, finishing crown preparations, contouring bone, removing impacted teeth, and separating crowns and bridges. Carbide burs are defined by their shank and by their head. The type of handpiece being used determines which type of shank is needed. The procedure to be performed determines the type of cutting design/head shape that is chosen.
