These are heavy duty center punches made from S7 shock resistant tool steel. These punches will hold a point for a very long time if used properly. The steel is very tough and holds up well. With the bigger heavier punch it doesn’t bounce as easily and more energy is transferred to the point. 

The handle measures just shy of an inch across the flats, is about 6” long and weighs about 13 ounces. 

The sale is per one punch. The picture is a whole batch. They all vary slightly from one another.
