These carbide burs are designed to provide maximum strength and reduce the risk of breakage. The shank of the bur is made out of stainless steel and the cutting end is brazed to the neck of the instrument, minimizing the likelihood of breakage. The burs are available in regular carbide burs and trimming and finishing burs. Carbide burs are packaged in easy-to-peel single packs, 5-packs (handpiece burs only), 10-packs, and the popular clinic pack bag (100 per package). For more information, call (866) 854-8300.
