Burs are an important aspect of any rotary tool. The bur you use will make the job easier, faster, and better. It is very important that you buy only the top quality burs. Our burs are made for dental professionals. They have been through stringent testing and will provide a vibration-free cutting. The shank is made of high tensile stainless steel precision made for perfect concentricity with ideal surface finish. Diamond bur particles are bonded by means of electroplating with uniform size and exceptionally sharp-edged diamonds. Be wary of bargain diamond burs which may not be straight or made to high quality standards.
