New air pulse porting technology (patent pending) inside the control unit gives each handpiece excellent range of power with perfect control throughout an expanded range of impact speeds.
The GraverMach features 400 to 8000 strokes per minute, a newly developed throttle bias adjustment valve for tailoring throttle response to your work and a dual-stage precision air regulator.
Advanced ergonomics include front air pressure adjustment, quick change air couplings, rear mount throttle connection, and an advanced valve pulse unit that operates with virtually no noise or vibration.
The GraverMach has connections for two impact handpieces, plus an auxiliary air connection for other air tools including the GRS Ultra 850 rotary handpiece. Handpieces sold separately. All GraverMax and GraverMate handpieces can be used with this machine.
