Dentsply Maillefer’s tungsten carbide burs are cut from high tenacity, micro grain hard metal. After the cutting edges of the active part have been ground by a precision tool impregnated with fine grained diamond, each bur individually undergoes a strength test. Tungsten carbide burs are preferably used with a turbine or with a high speed handpiece. With the turbine, minimal pressure guarantees better efficiency of the bur.
A rotation speed of 300’000 rpm is recommended for burs up to No. ISO 010. For sizes ISO 012 and above, the recommended speed is between 150’000 and 200’000 rpm. Regardless of their diameter, burs which have an active part that is longer than 8mm must never be used at speeds in excess of 200’000 rpm.
