GRS 004-995 GraverMax G8® – Professional Pneumatic Engraving System
The GRS 004-995 GraverMax G8® is a professional pneumatic engraving system designed for precise, controlled hand engraving, jewelry engraving, stone setting, relief engraving, and detailed metalworking. With an expanded operating range of 400 to 8,000 strokes per minute, the GraverMax G8 provides smooth, responsive control for everything from delicate engraving to more demanding work.
The GraverMax G8 builds on the proven GRS GraverMax platform with upgraded controls, improved ergonomics, and enhanced pneumatic performance. A throttle-bias adjustment valve lets the engraver tailor the response of the handpiece throttle, while the advanced valve pulse unit operates with virtually no noise or vibration.
The system provides connections for two impact handpieces plus an auxiliary air connection for other compatible pneumatic tools, including the GRS Ultra 850 Rotary Handpiece. Handpieces and tools are sold separately.

Precision Control for Professional Engraving
The GraverMax G8 is designed to give engravers precise control over handpiece performance throughout an expanded range of impact speeds. The 400–8,000 SPM operating range makes the system versatile enough for delicate engraving while providing the responsiveness needed for more powerful applications.
The adjustable throttle bias is particularly useful for tailoring the feel of the handpiece to individual preferences and engraving techniques.
Two Handpiece Connections
The GraverMax G8 features two impact handpiece connections, allowing engravers to keep two compatible GRS handpieces connected to the system.
This makes it easy to switch between different handpieces for different applications without repeatedly disconnecting air lines.
Compatible GRS handpieces include a wide selection of Standard Handpieces, allowing the engraver to choose the combination of size, power, and grip that best suits their work.
Auxiliary Air Connection
An additional auxiliary air outlet provides a connection for compatible pneumatic tools, including the GRS Ultra 850 Rotary Handpiece.
This allows the GraverMax G8 to serve as a versatile air source for both impact engraving and compatible rotary applications.
Airtact Compatibility
The GraverMax G8 is Airtact compatible, allowing the system to be configured with GRS Airtact components for hand and foot control switching.
Airtact provides an alternative method of controlling handpiece power directly through the hand control system, giving engravers additional flexibility in how they operate their equipment. Airtact components are sold separately.
