-
No cord in the way: work anywhere the battery goes, no outlet needed
-
Speed for the job at hand: three settings run from a gentle touch to full power
-
One tool, every material: cuts, carves, and polishes wood, jade, metal, and plastic

-
Comfortable for long sessions: the lightweight build and heat dissipation keep it comfortable and help prevent fatigue
Bring a workshop-level engraving pen wherever inspiration strikes — there is no cord tying you to an outlet, so the work goes with you. Three precision speed settings let you match the tool to the material in your hand, from a light touch on wood to full power on metal. The battery runs for hours between charges, so a long carving session never gets cut short.
This cordless rotary tool draws power from a 35W pure copper motor and a rechargeable 18650 battery with dual USB and Type-C charging, so it is always ready to go. As an electric engraving pen it also runs on silent bearings for smooth, steady turning, and the chuck takes bits from 0.02 to 0.13 in (0.5 to 3.2mm), small enough for detail work and sturdy enough for metal. The nine-piece attachment kit covers grinding, cutting, sanding, and polishing, and the lightweight, heat-dissipating build keeps it comfortable to hold through a long project. The bits and blades are sharp, so keep the tool out of children's reach when it is not in use.
