The Gravermax G8 has a wider range of power and finer control from newly patented air pulse technology. It is quieter, more compact and more ergonomic than the original Gravermax. Today's expanded range of handpiece options helps all users from apprentice to top professional accomplish even more in far less time. Featuring selectable stroke speed, which lets you set a precise impact rate, the Gravermax has a more natural feel, greater comfort and better control. The new engineering of the Gravermax G8 makes all handpieces more effective over a wider stroke speed range resulting in greater confidence in use and less physical stress.
