The video shows a close-up of a metal rod being shaped by a machine. The rod is rotating at a high speed, and a tool is being pressed against it to create a groove. The metal shavings are flying off as the tool cuts into the rod. The machine appears to be a lathe or milling machine, and the rod is likely made of steel or another metal. The tool used is a cutting tool, which is designed to shape the metal by removing material. The video provides a detailed look at the machining process, showcasing the precision and skill required to create a smooth, even surface on the metal rod.
