Electrosurgery utilizes alternating current at radio frequencies to cut and coagulate. 
Using this method, the current enters the patient's body and the patient becomes 
part of the electrical circuit. This requires the use of a return, or indifference plate. 
This economically priced electrosurgical unit has 10 levels of output intensity, 
three operational modes (cut, coagulate, and cut/coagulate), and various choices of 
electrodes. 
The unit comes complete and ready-to-use with a handpiece, indifference plate, 
footswitch, and one of each electrodes. All accessories can also be ordered 
separately.

This line-powered micro drill will make easy work of grinding, finishing, 
cutting, and drilling bone, teeth, and other material. The high-torque 35,000 
rpm (maximum) motor is quiet and has minimal vibration which reduces 
wear on the motor and provides greater comfort for the user. It also features 
a forward and reverse switch, "E Type" handpiece, and handpiece holder. The 
handpiece has a removable nose cone that can be cleaned and sterilized. It 
accepts 3/32" and 2.33 mm bur shanks.  Unlike battery-powered drills, this 
unit will maintain consistent power for the duration of use. The wide range of 
speeds allows the user to control the amount of heat generation.
The following accessories are included with the Micro Drill System:
