This automatic center punch 32AU from Beta Tools is designed to mark or create a center point or hole in a workpiece. It serves the same function as a conventional punch without the need for a hammer. When you press the punch into the workpiece, it stores energy in a spring. It then releases this energy to create the mark on the workpiece with the tip. The impulse applied at the tip of the punch is quite repeatable, allowing for consistent markings. With its sufficient length, it is comfortable to use.
