    The 557 carbide bur is suitable for autoclaving and won't rust even after repeated sterilization.

    Carefully designed blade structure, rake angle, flute depth and spiral angulation combined with our specially formulated tungsten carbide results in the powerful cutting performance of our burs. Boyue dental burs are engineered to deliver the most efficient cutting rate & performance for the most popular procedures. 

    Boyue dental burs carbide cutting heads are made with high quality fine-grain tungsten carbide, which produces a blade that is sharper and wears longer compared to less expensive coarse grain tungsten carbide.
    Blades made of fine grain tungsten carbide, retain shape even as they wear. Less expensive, large particle tungsten carbide dulls quickly as the large particles break from the blade or cutting edge. Many carbide manufacturers use inexpensive tool steel for the carbide bur shank material.
    For shank construction, Boyue dental burs uses surgical grade stainless steel, which resists corrosion during sterilization processes used in the dental office.
