As the best-selling rotary engraving machine, the M20 is a custom engraving machine that can adapt to any purpose and fit any job. Small and lightweight, you can find a place for the M20 in every shop or event.
    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. Created for industry, the M20 design is a guarantee of its longevity and durability. Designed for customer safety and sleekness which enables it to fit in any retail store. Bringing these two elements into one machine gives the M20 the heart and inner workings of an industrial powerhouse, with the looks and design that shows well in luxury boutiques where customers can admire and watch as their purchase becomes one of a kind.
    With many accessories, any version can easily be upgraded to fit the evolution of businesses and customers' needs. The M20 is the ideal solution for ring engraving (inside and outside of rings), jewelry engraving & pendants, personalizing gift items (pens, keyrings, perfume engraving), engraving photos or logos (medals, lighters), making small signs (CE plate, brass plate engraving, name plate engraving and name-tags engraving, plaque engraving) and metal plate engraving.
