Never before has a pneumatic handpiece system given the user so much versatility and control. A remarkable technical breakthrough is the seamless combination of hand and foot control. Using one simple knob, the user can choose between hand or foot control, whenever desired. This allows optimal working comfort and precision in a wider range of creative jobs.

The GraverMach AT is wonderfully familiar to anyone who uses its predecessors such as the GraverMax, GraverMax SC, or the original GraverMach. With the expanded capability of precise, selectable hand control, this power tool is in a class by itself. The hand control technology is based on the GRS Airtact.

This advanced, patented air logic system provides hand power control without adding moving parts to the handpiece itself. The result is a rugged and intuitive way to control handpiece power by hand. When foot control is preferred, it is only seconds away. Just one simple selector knob instantly provides greater control, choice, and refinement while working. The ability to instantly change from hand to foot control, as desired, means new creative freedom and reduced stress.
