The Ironmaster Kennametal's next generation face mill

Iron is the most abundant element on earth by mass. For over twenty-five centuries it's been used to plow fields, build bridges, cook food, and wage war. Without iron, the Industrial Revolution would have gone nowhere, we would have no trains, automobiles, or machine tools today, and mankind would still be an agrarian society.
