Perforation machine die set is a tool for making holes in materials. It is frequently used to make holes for grommets, buttons, or other items. The die set consists of two components: the anvil, which is a flat surface that the die rests on while in use, and the die, which is a sharpened tool used to cut the holes. The anvil is used to keep the material in position while the die set is placed on top of the material to be perforated. The holes are then made by lowering the die onto the material and rotating it either clockwise or anticlockwise.
