Description
Built for Professional Jewelry Engraving and Precision Metalwork
The Tooltos 400–8000RPM Pneumatic Jewelry Engraving Machine is designed for jewelers, stone setters, and metal engravers who need controlled handpiece response for detailed metal work. With dual handpieces, foot pedal control, an integrated pressure gauge, and a built-in air filter, it supports engraving, texture work, bead-edge detailing, stone-setting preparation, and precision workshop applications.
⚠️ Air Compressor Required
This machine requires an external air compressor with 0.15–0.25 MPa working pressure. The air compressor is not included and must be purchased separately.
Air Compressor Compatibility
This engraving machine requires an external air compressor to operate. For best performance, use clean, dry, oil-free compressed air. If using an oil-type compressor, an oil-removal filter is recommended to help protect the internal air system.
- Required air pressure: 0.15–0.25 MPa
- Air compressor: Not included — must be purchased separately
- Air quality: Clean, dry, oil-free compressed air recommended
- A stable regulated air supply helps improve handpiece response and engraving consistency
Key Features
- 400–8000RPM Variable Speed Control — Wide speed range covers everything from slow, controlled detail work to fast surface engraving, with smooth adjustment via the front control panel.
- Dual Handpiece Design — Two ergonomic handpieces provide two-handed stability and control during engraving, helping reduce hand fatigue and support better control during detailed work.
- Foot Pedal Control — Controls handpiece activation and power response, keeping both hands on the workpiece and improving workflow efficiency during active engraving.
- Professional Pressure Gauge — Built-in gauge lets you monitor and adjust air pressure in real time for consistent engraving performance across different materials and engraving depths.
- Built-In Filter System — Integrated air filter removes moisture and contaminants from the air supply, protecting the internal mechanism and extending machine service life.
- One-Piece Stamped Metal Shell — Frosted metal construction provides a durable, professional-grade housing that resists workshop wear and maintains structural integrity over time.
Best For
- Professional jewelers doing detailed engraving on rings, pendants, and bracelets
- Metal engravers working on gold, silver, copper, and brass surfaces
- Watch repair technicians needing precision engraving on small components
- Jewelry designers adding surface textures, patterns, and custom lettering
- Workshops requiring hands-free speed control for high-volume engraving work
Not For
- Users without access to an air compressor — this machine requires 0.15–0.25 MPa air pressure to operate
- Engraving on very hard metals such as hardened steel or titanium — performance depends on the engraving bit used
- Hobbyist or occasional single-piece use — this machine is designed for professional workshop environments

Quick Start Guide
- Connect air supply — Attach the connection tube to your air compressor. Set compressor output to 0.15–0.25 MPa.
- Connect power — Plug in the power cord and connect the foot pedal.
- Install engraving bit — Insert your engraving tip into the handpiece and secure it.
- Set speed — Adjust the speed control dial to your desired RPM for the material and task.
- Check pressure gauge — Verify air pressure is within the 0–4 kg/cm² operating range.
- Begin engraving — Press the foot pedal to activate the handpiece. Use both handpieces for stability and control.
- After use — Release foot pedal, power off, and disconnect air supply before removing the engraving bit.
Pro Tips
- Start at a lower speed when working on a new material or unfamiliar piece — increase RPM gradually once you confirm the engraving depth and response.
- Use the foot pedal to control handpiece power rather than applying extra hand pressure — this gives you more consistent depth control and reduces tip wear.
- Check and drain the built-in filter regularly — moisture buildup in the air line reduces machine performance and can damage internal components over time.
- Keep your air compressor pressure consistent — pressure fluctuations above 0.25 MPa can affect engraving speed stability and tip wear.
Frequently Asked Questions
Is an air compressor included?
No. This machine requires an external air compressor with 0.15–0.25 MPa working pressure. The compressor must be purchased separately. Please confirm your compressor output before ordering.
Which voltage should I select?
Select 110V for US and Canada. Select 220V for Europe, Asia, Australia, UK, and most other international markets. Please confirm your local voltage before ordering.
Can this machine engrave hard metals like steel or titanium?
Performance on very hard metals depends on the engraving bit used. This machine is optimized for jewelry metals including gold, silver, copper, and brass. For hardened steel or titanium, use appropriate carbide or diamond-tipped engraving bits.
How do I control the engraving speed?
Speed is adjusted via the front control panel dial, which covers the full 400–8000 RPM range. The foot pedal controls handpiece activation and power response — speed range adjustment is done manually on the machine.
What is the purpose of the dual handpieces?
The two handpieces allow two-handed operation, providing greater stability and control during fine detail engraving. This helps reduce hand fatigue and supports better control on small or intricate workpieces.
How often should I clean the filter?
Check the built-in filter after every 8–10 hours of use. Drain any accumulated moisture and replace the filter element when it shows signs of contamination or reduced airflow.
What engraving bits are compatible?
This machine is compatible with standard pneumatic engraving bits. Bit selection depends on the material and engraving style. Refer to the included instruction manual for recommended bit types and sizes.
