PHYHOO Jewelry Pneumatic Engraving Machine | Dual Handle 400-8000 RPM

Professional pneumatic jewelry engraving machine with dual handles and foot pedal speed control — delivering 400–8000 RPM precision for metal engraving, stone setting, and surface texturing in jewelry studios and repair shops.

Key Selling Points

• Dual Pneumatic Engraving Handles — two handpieces included for switching between engraving styles or sharing the machine between workstations without reconfiguration
• 400–8000 RPM Adjustable Speed — foot pedal control delivers real-time, hands-free speed adjustment, keeping full focus on the workpiece throughout every stroke
• Professional 0–60 PSI Pressure Gauge — precision regulator allows exact pressure selection for fine detail work or deep carving, ensuring consistent engraving depth across every piece
• Built-in Metal Impurity Filter — captures metal particles generated during engraving to protect internal components and maintain consistent operating speed over time
• One-Piece Frosted Stamped Shell — no welding seams, waterproof construction, and built for daily professional use in high-output studio environments
• Dual Voltage 110V and 220V — compatible with workshops worldwide, no external converter required

About This Product

The PHYHOO HH-G01 is a pneumatic engraving machine designed for professional jewelers who require precise, repeatable control over engraving depth and speed. Unlike rotary electric engravers, the pneumatic mechanism delivers a consistent impact-driven stroke that reduces hand fatigue during extended engraving sessions and produces cleaner cuts on hard metals.

The foot pedal connects directly to the rear jack for hands-free speed control, while the intuitive control panel with mechanical pointer display allows quick adjustments without interrupting workflow. Requires an external air compressor (not included) with a clean, dry air supply.

Pro Tips

• Start at 20–25 PSI for fine detail engraving and increase pressure in 5 PSI increments for deeper cuts. Test on a scrap piece of the same metal before working on the final piece to calibrate depth and stroke.
• Use the foot pedal to modulate speed mid-stroke rather than pre-setting a fixed RPM. Slowing down at corners and curves gives cleaner line definition and reduces the risk of overcut on fine detail work.
• Ensure your air compressor delivers clean, dry air. Moisture in the air line is the leading cause of internal component damage. Install an inline moisture trap between the compressor and the machine if your compressor does not have a built-in dryer.
• Clean the impurity filter after every 4–6 hours of use. A clogged filter reduces air flow, causing inconsistent handpiece speed and uneven engraving depth. Tap the filter housing gently to dislodge metal particles before blowing clean with compressed air.
• When switching between the two handpieces, disconnect air pressure first. Never swap handpieces under pressure — this can damage the connector fittings and cause sudden air release that may injure the operator.

Frequently Asked Questions

Does this machine include an air compressor?
No. An external air compressor is required for operation and is not included. The compressor must supply clean, dry compressed air. A moisture trap or inline dryer is strongly recommended to protect internal components from moisture damage.

Is this a rotary engraver or a pneumatic impact engraver?
This is a pneumatic impact-driven engraver, not a rotary electric tool. The handpiece delivers a rapid impact stroke driven by compressed air, which reduces hand fatigue and produces cleaner cuts on hard metals compared to rotary engravers.

Can it engrave materials other than metal?
This machine is optimized for hard metal jewelry applications including gold, silver, platinum, and brass. It is not designed for wood, plastic, acrylic, or other soft materials, where the impact mechanism may cause cracking or uncontrolled material removal.

What is the maximum operating pressure?
The maximum operating pressure is 60 PSI. Do not exceed this limit. For most jewelry engraving tasks, 15–40 PSI is sufficient. Higher pressure increases impact force but reduces control over fine detail work.

Can both handpieces be used simultaneously?
No. The two handpieces connect to the same air supply and control unit. Only one handpiece can be operated at a time. The dual-handle design allows quick switching between different handpiece configurations without reconfiguration of the machine.
