About This Engraving Machine
The Tooltos Dual Handpiece Pneumatic Engraving Machine is designed for jewelers, stone setters, and engravers who need precise, controlled impact engraving without frequent bit changes. Two graver handpieces install simultaneously and switch via the selector knob, keeping workflow uninterrupted. The foot pedal provides stepless speed control from 100 to 4000RPM, while the adjustable air pressure regulator allows precise depth control for engraving, stone setting, stippling, and matte finishing on metal, stone, jade, and other materials.
Available in 110V for North America and 220V for international use. An external air compressor is required and is not included.
Best For / Not For

| Stone setting (bezel, pave, channel) | High-volume industrial engraving |
| Stippling and matte finishing | Rotary-only engraving applications |
| Workflows requiring two graver bits ready simultaneously | Engravers who only need a single handpiece setup |

Pro Tips
- Always verify the selector knob position before pressing the foot pedal to confirm which handpiece is active.
- Start with lower air pressure and increase gradually — lower pressure for delicate engraving and stone setting, higher pressure for harder materials.
- Use the dual handpiece setup strategically — keep one bit for cutting and one for finishing so you can switch instantly without stopping work.
- Check all air line connections before starting — air leaks cause inconsistent impact and pressure loss during engraving.
- Monitor the pressure gauge throughout a session to maintain consistent engraving depth across the entire workpiece.
Frequently Asked Questions
Does this machine require an air compressor?
Yes. An external air compressor is required for operation and is not included. A compressor capable of delivering at least 3 kg/cm2 (approx. 43 PSI) is recommended.
What is the advantage of the dual handpiece design?
Two graver handpieces can be installed simultaneously. Switch between them using the selector knob without stopping to change bits — ideal for workflows requiring multiple graver types in sequence.
Which voltage should I order?
Select 110V for North America (US, Canada, Mexico). Select 220V for Europe, Asia, Australia, and most other international locations. Ordering the wrong voltage will damage the machine.
Can this machine be used for stone setting?
Yes. The precise impact control and adjustable pressure make it well-suited for bezel, pave, and channel stone setting work.
Are graver bits included?
No. Graver bits and handpiece accessories must be purchased separately. Contact sales@tooltos.com for compatible accessory recommendations.
