Gravotech Engraving Station M20
As the best-selling rotary engraver, the Gravotech Engraving Station M20 can adapt to any purpose and fit any job. Small and lightweight, you can find a place for the M20 in every shop, workshop, and even take it on a promotion tour. Built for shops that need a reliable rotary engraving machine without a heavy footprint or steep learning curve, the M20 fits seamlessly into daily production.
Engraving has never been easier thanks to the M20, Bluetooth, simple control panel, multiple positioning vices, open design for easy parts loading and unloading, and our unique engraving assistance features (point & shoot, engraving preview, automatic height measurement, surface tracking, etc.). This rotary engraving machine benefits from a new sturdy bridge and a stronger spindle. With many accessories, any version can easily be upgraded to fit the evolution of businesses and customers' needs. Long-time customers may recognize this machine under its legacy name, the Gravograph M20 — Gravotech unified the Gravograph and Technifor lines under one brand in 2020/2021, so it's the same trusted engraving station, just a new name on the box.

Frequently Asked Questions
- What is the Gravotech M20 used for?
- The Gravotech M20 is a compact rotary engraving machine used for jewelry personalization, pet tag engraving, ID tags, awards, and industrial nameplates. Its small footprint and Bluetooth connectivity make it ideal for jewelry counters, promotional events, and small-batch production across aerospace, automotive, and industrial marking applications.
- Is the Gravotech M20 the same as the Gravograph M20?
- Yes. Gravograph and Technifor were unified under the single Gravotech brand in 2020–2021, so the Gravotech M20 and Gravograph M20 refer to the same machine. Older catalogs, quotes, or equipment may still reference the Gravograph name, but the engraving station and support remain unchanged.
- What materials can the Gravotech M20 engrave?
- The M20 rotary engraving machine handles metals, plastics, and other rigid substrates commonly used for jewelry, ID tags, nameplates, and awards. Specialized cutters and diamond tips allow it to personalize fine jewelry, while its open design and positioning vices support a wide range of part shapes and sizes.
- How is the Gravotech M20 different from the IS200 or IS400?
- The M20 is Gravotech's best-selling rotary engraver, built for lightweight portability and jewelry/tag work. The IS200 and IS400 are CNC stations designed for larger-scale industrial part traceability, signage, and light milling. Choose the M20 for mobility and simplicity; choose an IS-series station for higher-volume production.
- Where can I buy a Gravotech M20 rotary engraving machine?
- Big City Manufacturing carries the full Gravotech M20 lineup, along with GravoStyle software, accessories, and ongoing support. Since 1976, Big City has supplied identification and marking equipment to businesses nationwide — contact the team for current pricing, configuration guidance, and quotes tailored to your engraving needs.
