The video shows a machine with a rotating bit carving out a circle on a black surface. The machine is white and has a metal bit that is spinning at a high speed. The black surface appears to be made of a hard material, possibly metal or plastic. As the machine carves out the circle, small pieces of the material are being removed and scattered around the area. The machine is moving in a circular motion, and the circle being carved out is becoming more defined with each pass of the bit.
