Mini Cordless Electric Grinder Pen With Built-in Battery

Mini Cordless Electric Grinder Pen With Built-in Battery is a very helpful tool for DIY jobs. Helps me a lot with 3d prints, grind traces on PCB boards and my RC car build. No tools are needed just insert the grinding attachment and press the start button. It has 3 speeds with overload protection. Can be operated while charging. Please note this pen is for fine precise jobs so don’t expect it to be super powerful. For that, I have this Rotary tool here to grind whatever you will need.
