Embodiment Construction

[0065] figure 1 A first drill bit 101 of a preferred embodiment of the invention is shown. The drill bit 101 includes a shank 103 having a tapered end 105 forming a bit tip. The material from which the drill bit 101 is made depends on the application requirements of the drill bit 101 . However, for plastic surgery, the drill bit 101 is made of surgical quality stainless steel. Although not shown in the figures, the other end of the drill bit 101 is adapted to be mounted in a motorized chuck. For example, the other end of the drill bit 101 may be provided with a series of graduations, cut-outs and annular grooves located adjacent to the other end of the drill bit of the stem 103 to facilitate the connection of the other end to the chuck of the driver of the motorized surgical drill bit. The scale can be used to indicate the depth of insertion of the drill into the drive chuck and into the patient.

[0066] The drill bit 101 also includes one or more grooves in the form of g...
