Pneumatic Jewelry Engraving Machine | Dual Handpieces with Foot Pedal
A bench-top pneumatic engraving machine built for controlled metal engraving, bead-edge detailing, surface texture work, and stone-setting preparation. Variable 400–8000 RPM speed, foot pedal activation, dual handpieces, a front pressure gauge, and a built-in air filter support steady, hands-free bench work when connected to a suitable external compressor.
The one-piece frosted metal shell houses a 100W motor with universal voltage compatibility. Whether you are engraving rings, finishing pendants, or preparing stone settings, the foot pedal keeps both hands on the workpiece while the front panel lets you dial in the exact RPM for the task.
Air Compressor Setup Guide
| Setup Point | Guidance |
|---|---|
| Required air pressure | 0.15–0.25 MPa from an external compressor |
| Air quality | Clean, dry, oil-free air recommended. Add oil-removal filtration if using an oil-type compressor. |
| Pressure monitoring | Use the front gauge to check pressure during setup and operation. |
| Before ordering | Confirm compressor output, plug compatibility, and engraving bit compatibility for your workflow. |
Best For / Not For
| Best For | Not For |
|---|---|
| Jewelry engraving on rings, pendants, bracelets, and small metal pieces | Users without access to a compatible external air compressor |
| Gold, silver, copper, and brass surface work with suitable engraving bits | Heavy material removal on hardened steel, titanium, or very hard alloys |
| Stone-setting preparation, bead-edge detailing, and decorative texture work | Portable or cordless engraving away from power and compressed air |
| Bench-top jewelry workshops needing foot-controlled, hands-free activation | Buyers expecting an air compressor or engraving bits to be included |

Pro Tips
- Start at a lower RPM on any new material, then increase gradually after checking cut depth and handpiece response.
- Keep compressor output within 0.15–0.25 MPa — pressure outside this range affects engraving consistency and can stress the pneumatic system.
- Use clean, dry air and inspect the built-in filter regularly, especially during longer bench sessions.
- Secure small jewelry pieces with an appropriate fixture or vise before engraving to improve control and line consistency.
- Disconnect both power and air before changing engraving bits or performing any maintenance on the handpieces.
Frequently Asked Questions
Is an air compressor included?
No. This machine requires an external air compressor set to 0.15–0.25 MPa. The compressor must be purchased separately and is not included.
Does it support universal voltage?
Yes. The machine is rated for universal voltage, but confirm plug compatibility and safe connection for your local power supply before use.
How is engraving speed controlled?
Speed is adjusted on the front control panel across the 400–8000 RPM range. The foot pedal controls activation and working response during engraving, keeping both hands free.
What materials can it engrave?
It is designed for jewelry metals including gold, silver, copper, and brass when used with suitable engraving bits. Performance on very hard metals such as hardened steel or titanium depends on the bit and setup.
Are engraving bits included?
Engraving bits are not included. Select bits according to your material, engraving style, and handpiece compatibility.
What should I check before ordering?
Confirm compressor output (0.15–0.25 MPa), plug compatibility, clean dry air availability, required engraving bits, and whether the 29 x 13 x 21 cm machine size fits your bench. Contact the Musttool team at musttool01@gmail.com if you have pre-purchase questions.
