The Model Expo Cordless Mini Rotary Tool is a pen-sized, USB-rechargeable grinder with five speeds from 5,000 to 18,000 RPM and a 3.7V battery rated for up to 200 minutes of continuous use. It ships with 60+ accessories for engraving, sanding, grinding, polishing and cutting, plus an LED at the bit for dim work. It suits light craft and detail jobs where a full-size corded rotary tool is overkill. Against Dremel-class tools it trades torque and top speed for cordless convenience and a low price tier; expect it to stall on hard materials that a mains-powered tool handles easily.

This is a cordless mini rotary tool that recharges by USB. It is small enough to hold in one hand and is used for engraving, sanding, grinding, polishing and cutting. The set includes 60+ accessories.
The tool is light and is held like a pen, which gives control over pressure and comfort during delicate DIY jobs. An LED indicator light on the tool helps in dim light or hard-to-see spots and reduces shadows.
A 3.7V rechargeable battery runs the tool continuously for up to 200 minutes. It has 5 adjustable speeds, from 5000 to 18000 RPM, to suit different tasks. Avoid charging for too long or overloading the tool.
