New marathon N7 complete unit
* The handpiece operates at 40,000rpm
* The controller has a dial knob so you can change speeds
* The foot pedal can be connected to the controller so you can vary the speed with the foot pedal and have both hands free
* The control box comes wired for 110 volts or 220 volts, it has an adaptor if you have EURO power or American
* The handpiece is light in weight and is used by allot of my Dental Lab accounts and they are very pleased with the results and its durability, some have been in service over 2 years without a problem
* As you can see by the picture it comes with extra wrenches to change the chuck and extra set of brushes
* It also comes with my 1 year warranty from the date of purchase
* I have ordered the adaptor to change the bur size so that you can use the same burs you are using on your high speed air driven NSK presto, so in essence you will be able to use 1 handpiece and multi bur types and with the adaptor you will be able to use your existing burs
