The Endy NT2 enables you to adjust the speed for your file from 250 to 1,200 rpm using the same contra-angle handpiece. A single machine is all you need to treat all of your root canal enlargements.
The speed of the Endy NT2 remains constant regardless of the force applied to the file in the root canal. It will not vary, even if the battery is charged less than 50%. The torque is controlled continuously in order to preserve your files.
