The MT-20 is a high end, reliable tabletop electric file. The lightweight hand piece is slim and fits perfectly in your hand. The weight is distributed evenly so the back end of the hand piece will not strain your wrist. The smart micromotor design is the only hand piece with the perfect balance of RPM and TORQUE. Therefore, the hand piece will never bog down and it will maintain its set RPM when pressure is applied.
RPM = speed
Torque = power
The MT-20 hand piece has high torque which also allows you to file at low speeds without bogging down. The quick, twist lock chuck makes changing bits easy and ensures that bits are safely locked into place while filing,
