Shank Solid Carbide Bur

The balance between hardness and toughness in Solid Carbide Burs is largely determined by their material composition and microstructure. Typically, these burs are made from tungsten carbide particles bonded with a cobalt matrix. Increasing the tungsten carbide content generally enhances hardness but reduces toughness, while a higher cobalt binder improves toughness at the expense of hardness. Manufacturers carefully adjust this ratio to meet specific application demands, tailoring burs to different materials and cutting conditions.
