The GRS GraverMach pneumatic engraving system can run two handpieces as well as an auxiliary air connector for other air tools, such as the GRS Ultra 850 Rotary handpiece (TOOLSGR151). This gives each handpiece excellent range of power with perfect control throughout an expanded range of impact speeds.
With the expanded capability of precise, selectable hand control, this new power tool is in a class by itself. The new GraverMach is wonderfully familiar to anyone who uses its predecessors such as the GraverMax, GraverMax SC or the original GraverMach. 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 foot pedal has been redesigned, the increased size for enhanced useability and the re-engineered to require less maintenance this ensures both durability and comfort. The ability to instantly change from hand to foot control, as desired, means new creative freedom and reduced stress. This GraverMax has optimized controls, the separated speed at power controls allows users to easily adjust their cutting speed while accessing full power through the foot pedal. This foot pedal has been redesigned, the increased size for enhanced useability and the re-engineered to require less maintenance this ensures both durability and comfort.
The GraverMax has a new high-quality brushless DC motor, ensuring greater longevity. The motors have been strategically mounted to protected against damaged from oil or water infiltration. The GRS pneumatic power tools require oil-free compressed air with a minimum of 3 bar pressure and 40 litres a minute. If an oil-lubricated compressor is being an Air Filter has been attached to the back of the unit. This GraverMax is supplied without a handpiece allowing this unit to be adapted to desired use.
