Electric Handpiece

I need to…


Electric handpieces offer never-ending torque yet require a high initial and continued maintenance cost.

Complete overhauls are not necessary due to the structure of electric handpieces. This is different from it’s air-driven counterpart. Yet a common source of malfunction in any handpiece is the ball bearings. Dentool uses ceramic ball bearings in its repairs adding to the longevity of the handpiece.
Other parts prone to breakdown include gears, the spindle, and/or the drive shaft. Upon proper evaluation, malfunctioning components will be noted for repair. Again, because a complete overhaul is not necessary only those parts broken or malfunctioning will be replaced.
Electric handpiece repairs begin at $250 and when used under OEM standard guidelines, include a 90 day warranty .


Electric Handpiece Maintenance & Tips

  • Costly Gear Repairs occur when a handpiece is used after the bearings start to breakdown, therefore the shaft no longer rotates on its correct axis.  This puts gears in a bind and causes rapid wear resulting in handpiece failure and high repair costs.
  • STOP using your electric handpiece as soon as you feel an unusual vibration or hear an unusual noise. This could save you hundreds of dollars in repairs.
  • Coarse burs also cause damage to gears with excessive vibration which is not a problem in air driven highspeed handpieces because of feathering. But in the electric highspeed the added torque available allows the user to keep the bur in constant contact with the tooth surface. The vibration caused by the coarse bur is transmitted directly back to the bearings causing rapid bearing failure. Therefore eventual gear damage.
  • Extend the life of electric handpiece by making sure you have enough drive air pressure used to cool the motor and the attachment. Consult the manufacturer’s recommendation for proper PSI settings. We recommend having at least 65 PSI at the dental unit.
  • Be sure to use as much chip air and water while the handpiece is in use to cool the bearings within the head prolonging the bearings life span.
  • Manufacturers replace all internal drive parts regardless the problem, causing excessive repair costs, even if only one bearing or water line seal is bad.
  • Independent repair centers, such as Dentool, can do a minor rebuild that involves replacing just the needed parts for a much lower cost extending the time before a major rebuild is required.


Minimize your Electric Handpiece Repair Costs by

  1. using fine to medium burs
  2. running the manufactures PSI air settings
  3. using as much Chip Air and Water as possible
  4. seeking a minor rebuild as soon as there is any problem
