Pneumatic Jewelry Engraver GraverMax G8

Execute precise pneumatic impact engraving, stone setting, channel cleaning, and milgrain detailing with seamless dual-tool capability. The GraverMax G8 Pneumatic Jewelry Engraving System (Model: HH-G01) features a dual-port pneumatic console that supports two impact handpieces simultaneously, plus an independent auxiliary air line. Engineered to deliver a wide impact speed spectrum from 400 to 8,000 SPM and air pressure regulation from 0 to 60 PSI (0 to 0.4 MPa), this workstation allows bench jewelers to toggle instantly between coarse metal carving and delicate pavé bead raising.

Why Choose the GraverMax G8 (HH-G01) Pneumatic System

• Dual Handpiece Outlets + Auxiliary Air Port: Outfitted with two primary quick-connect ports to toggle between two impact handpieces without changing tools, plus a dedicated rear AUX port for secondary pneumatic tools like air scribes or chip blowers.

• Wide Impact Speed Spectrum (400–8,000 SPM): Front-panel speed control dial regulates impact pulse rates, enabling smooth transitions between fine line bulino shading and heavy background metal removal.

• 0–60 PSI Precision Air Pressure Regulation: Top-mounted regulator knob and front-facing pressure gauge (0 to 4 kg/cm²) ensure steady, calibrated air pressure for consistent stroke force and depth.

• Throttle Bias Fine-Tuning: Features an adjustable BIAS control knob that tailors initial throttle response and stroke sensitivity to match individual handpiece weights and jeweler preferences.

• Seamless Shell Design & External Water Filter: Constructed with a frosted, thickened stainless steel chassis formed by one-time stamping without welds, complete with a side-mounted moisture filter to keep air supply clean and oil-free.
