The 2UUL DA84 CVT Grinder Pro is a precision mini grinding and drilling tool designed mainly for mobile phone motherboard repair, PCB modification, and micro-polishing work. It is a pen-style electric grinder that allows technicians to perform delicate operations such as polishing IC edges, removing glue residue, and shaping phone frames during repair.
The grinder features a continuously variable speed (CVT) control system, allowing users to adjust the rotation speed smoothly depending on the task. The motor can reach speeds of up to about 18,000 RPM, which provides enough power for grinding, drilling, polishing, or cleaning small electronic parts without damaging nearby components.
One of its main advantages is its cordless rechargeable design. The tool contains a 3400 mAh lithium battery and is usually charged through a USB Type-C port, making it convenient to use at repair benches or during field repairs without dealing with cables. The pen-shaped ergonomic body provides good control and reduces hand fatigue when performing precise micro-repair work.
