PHYHOO HH-G03 Dual Control Pneumatic Engraving Machine | Foot and Hand Pressure

A bench-top pneumatic engraving machine with dual pressure-control modes for jewelry workshops that need precise, adaptable control — switch between foot-pedal activation (0-60 PSI) and hand-control regulation (0-30 PSI) without changing the setup.

Key Selling Points

• Dual pressure-control modes — foot control (0-60 PSI) for hands-free bench work; hand control (0-30 PSI) for direct front-panel regulation. Switch between modes without changing the setup.
• Variable 400-8000 RPM speed control — dial in the exact RPM for engraving, texturing, bead-edge detailing, or stone-setting prep on gold, silver, copper, and brass.
• Multi-knob front panel — independent controls for speed, foot-control pressure, and hand-control pressure in one compact bench-top unit.
• Dual handpiece size options — choose metric 6.0 mm or imperial 6.3 mm to match your existing engraving bits and tooling standard.
• Built-in air filter/regulator — protects the pneumatic system from moisture and debris; maintains consistent airflow throughout each session.
• 110V and 220V versions available — select the correct voltage for your region before ordering; not interchangeable after purchase.

About This Product

The PHYHOO HH-G03 is a bench-top pneumatic engraving machine designed for jewelers who need flexible pressure control across different engraving tasks. The multi-knob front panel provides independent adjustment of speed (400-8000 RPM), foot-control pressure (0-60 PSI), and hand-control pressure (0-30 PSI), allowing operators to switch working modes without reconfiguring the machine.

Two handpiece size options (6.0 mm metric and 6.3 mm imperial) support 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.
• Start with conservative pressure settings on a new material, then increase gradually within the foot-control or hand-control range.
• Use clean, dry compressed air and inspect the air filter/regulator before each session.
• Choose your handpiece size (6.0 mm or 6.3 mm) before ordering compatible engraving bits.
• Disconnect both power and air before changing bits, adjusting fittings, or inspecting handpiece connections.

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 0-60 PSI working range.

What is the difference between foot control and hand control?

Foot control regulates pressure from 0-60 PSI and activates the handpiece via the pedal, keeping both hands free. Hand control regulates pressure from 0-30 PSI and is operated directly from the front panel. Use whichever mode suits your working style and task.

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.

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.

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 should I prepare before ordering?

Confirm your voltage (110V or 220V), handpiece size (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.
