Rechargeable Mini Rotary Tool — Variable Speed USB Grinder for Wood, Jade, Metal & Craft DIY
Precision work shouldn't require a heavy, wired workshop. This upgraded mini electric rotary tool packs a customized high-power motor and a built-in cooling fan into a slim, palm-fitting body, giving you smooth carving, engraving, polishing and cutting power right in your hand. With an adjustable speed range of 3600–18000 r/min, you can fine-tune the rotation to match wood, jade, metal or glass.
The full-copper thick-wall chuck grips drill bits and accessories tightly from 0.5 to 3.2mm with no slipping, and swaps between grinding tips in seconds. Powered by a built-in rechargeable lithium battery, it works cordlessly anywhere — or plug in the USB cable for non-stop wired use on longer jobs. The ergonomic anti-slip body stays comfortable through hours of detailed DIY, whether you're carving a wooden sculpture, polishing jewelry, cleaning rust off metal, or trimming models. Compact at just 169×31mm, it slips easily into a drawer or tool bag. Powerful, portable and precise — professional-grade crafting made effortless at home.
