GRS Tools

Never before has a pneumatic hand-piece system given the user so much versatility and control. The seamless combination of hand and foot control is a remarkable technical breakthrough. Whenever desired, the user can choose between hand or foot control with one simple knob. This allows optimal working comfort and precisionin a wider range of creative jobs.

The new GraverMach AT is wonderfully familiar to anyone who uses its predecessors including the GraverMax, GraverMax SC or the original GraverMach. But the expanded capability of precise, selectable hand control puts this new power tool in a class by itself. The hand control technology is based on the GRS Airtact. This advanced (patent pending) 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. But remember, when foot control is preferred, it’s only 2 seconds away.

It’s one simple selector knob, but it instantly gives you greater control, choice and refinement in your work. The ability to instantly change from hand to foot control whenever you want means new creative freedom and reduced stress.

Each includes a foot control and air filter, and requires clean, oil-free compressed air with minimum 45 psi (3 bar) pressure and 1.4 cfm (40 liters per minute) flow. Electrical requirements are 100/240 V at 50/60 Hz. All Standard Systems have a stroke speed of 400-8000 strokes per minute (SPM). Handpieces sold separately. Note the main differences below.
