A compact bench-top pneumatic engraving machine for jewelry workshops — with dual handpieces, foot pedal control, 0-45 PSI pressure regulation, and variable 400-8000 RPM speed for precise hands-free engraving, finishing, and stone-setting preparation.
Key Selling Points
- Variable 400-8000 RPM speed control — dial in the exact RPM for engraving, texturing, or stone-setting prep on gold, silver, copper, and brass.
- 0-45 PSI pressure regulation — built-in air filter/regulator lets you fine-tune air pressure for consistent, controlled handpiece performance.
- Foot pedal activation — keeps both hands on the workpiece for improved control and line consistency during bench work.
- Dual pneumatic handpieces included — choose metric 6.0 mm or imperial 6.3 mm to match your existing engraving bits and tooling setup.
- Compact handled control unit — 27 x 14 x 22.5 cm body with top carry handle; easy to position and reposition on any bench.
- 110V and 220V versions available — select the correct voltage for your region before ordering; not interchangeable after purchase.
About This Product
The PHYHOO HH-G02 is a bench-top pneumatic engraving machine designed for jewelers and metal artisans who require consistent, controlled engraving on small metal pieces. The 400-8000 RPM speed range and 0-45 PSI pressure regulation give precise control over handpiece performance, while foot pedal activation frees both hands for workpiece handling.
The compact control unit includes a top carry handle for easy bench positioning. Two handpiece size options (6.0 mm metric and 6.3 mm imperial) allow compatibility with different engraving bit standards. An external air compressor is required and not included.
Voltage Selection Guide
Select the correct voltage for your region before ordering — using the wrong voltage will damage the motor and void any service support.
- 110V 60Hz — North America, Japan, Taiwan, and other 110V regions
- 220V 50Hz — Europe, UK, Australia, China, and most of Asia/Africa

Pro Tips
- Confirm 110V or 220V before ordering — the power version cannot be changed after purchase.
- Choose your handpiece size (6.0 mm or 6.3 mm) before ordering compatible engraving bits.
- Use clean, dry compressed air and inspect the air filter/regulator before each session.
- Secure rings, pendants, and small metal pieces in a suitable fixture before touching the bit to the surface.
- Disconnect both power and air before changing bits, adjusting fittings, or inspecting the handpiece connection.
Frequently Asked Questions
Is an air compressor included?
No. A compressor is required for operation but is not included. Ensure your compressor output is within the 0-45 PSI working range.
What is the difference between the 6.0 mm and 6.3 mm handpiece options?
6.0 mm is the metric standard common in Europe and Asia; 6.3 mm (1/4 inch) is the imperial standard common in North America. Choose the option that matches your existing engraving bits.
What voltage should I order?
Order 110V 60Hz for North America, Japan, and Taiwan. Order 220V 50Hz for Europe, UK, Australia, China, and most of Asia and Africa. If unsure, check the label on any household appliance.
Are engraving bits included?
Engraving bits are not included. Select bits according to your material, engraving style, and handpiece size (6.0 mm or 6.3 mm).
What materials can it engrave?
Designed for jewelry metals including gold, silver, copper, and brass. Performance on very hard metals depends on the engraving bit and setup.
What should I prepare before ordering?
Confirm your voltage (110V or 220V), handpiece size preference (6.0 mm or 6.3 mm), compressor availability, and required engraving bits. Contact the PHYHOO team at sales@phyhoo.com if you have pre-purchase questions.
