PIE5OELECTRIC

/- Operates in 25,000 to 50,000 cps. 2. Activated by dimensional changes in crystals

housed within the hand piece as electricity

is passed over the surface of the crystals.

3.Produces linear tip movement which allows

only 2 sides of the tip to be active at a time.

A variety of insert tip designs and shapes are

available.
