Dentist has recognised that the pains during treatment could be reduced significantly if the drill bit be able to reach an extremely high rotating speed. As far as the… Read the rest

With the development of the medical technology, nowadays there are many designs of dental drills available, however, each have the same basic features, including turbine, a handpiece, couplings, and a drill bit. The high speed drilling is activated by an air turbine. These devices convert highly pressurized air into the mechanical energy, enabling drill bits to rotate over 300,000 to 450,000 rpm.

The drill bit, is the most important part of the dental drill. It is short and highly durable, able to withstand high speed rotation and the heat that… Read the rest
