About This Inside Ring Engraver

The Tooltos Inside Ring Engraver Machine is a professional manual engraving tool designed for jewelers, goldsmiths, and custom jewelry studios that need to add personalized text to the inside of rings quickly and accurately. The diamond nib pen traces letter block characters from the dual-sided plate, transferring clean 1.5mm or 2.0mm lettering directly onto the ring interior.

The 360-degree rotating jaw holds narrow, wide, and set rings securely while the adjustable aluminum alloy base keeps the machine level on any workbench. No electricity, no steep learning curve — consistent inside-ring engraving from the first use.

Pro Tips

• Clean the ring interior first — Wipe with a polishing cloth to remove oils before engraving; oils cause the nib to slip and produce uneven lines.
• Practice on a copper test ring — Run through the full letter sequence on scrap metal before engraving a finished piece.
• Apply light, consistent pressure — Let the diamond nib do the work rather than forcing it; excessive pressure causes gouging and uneven depth.
• Match plate size to band width — Use the 1.5mm plate for narrow bands and the 2.0mm plate for wider shanks to maintain visual proportion.
• Level the base before starting — Adjust the foot height until the machine sits perfectly level; an unlevel base causes uneven engraving depth across the character run.

Frequently Asked Questions

Can this machine engrave the outside of a ring?
No. This tool is specifically designed for inside ring engraving. The diamond nib and jaw geometry are optimized for interior surfaces only.

What character sizes are available?
The dual-sided letter block plate provides 1.5mm and 2.0mm character heights, supporting English letters and Arabic numerals. Characters smaller than 1.5mm are not supported.

Can it engrave steel or titanium rings?
No. This engraver is designed for non-ferrous metals: gold, silver, copper, and platinum. Steel and titanium are too hard for the diamond nib at manual pressure.

Can it engrave set rings with stones?
Yes. The 360-degree rotating jaw accommodates narrow, wide, and set rings. Take care to avoid contact between the nib and any stones during engraving.

Does this tool require electricity?
No. This is a fully manual engraver. The jeweler guides the diamond nib pen by hand, giving complete control over depth and pressure with no power source needed.
