SmartPro Air Do X Stonesetter, Engraver & Micromotor

The SmartPro Air Do X is a bench power unit for stone setting and light engraving that puts a pneumatic engraver and a high-speed micromotor in one compact housing, with a built-in compressor so there is no separate air supply to buy or maintain. Best Built supplies it with digital LED controls, overload protection, and both hand and foot control for precise, repeatable work.

It covers prong, bezel, and pavé stone setting, light engraving on precious metals including gold, and drilling, deburring, polishing, and general bench work, which makes it an all-around power tool for jewelers who need versatile bench capability without running several machines. It is made in South Korea.

Features

• Two tools in one: Pneumatic engraver and 35,000 RPM micromotor in a single unit saves bench space and simplifies setup.
• Integrated air system: An internal pump delivers stable air pressure, so no external compressor is required.
• Wide speed range: 240–8,000 SPM engraving strokes, with variable micromotor speed up to 35,000 RPM.
• Digital LED controls: Clear speed and mode display with quick tool selection, overload protection, and emergency stop.

• Built to last: Compact, reliable construction designed for long service life.

Compatibility

• SmartPro collets are not interchangeable with GRS collets because the outside diameters differ.
