This is a center punch that is made to work in conjunction with the drill jig and drill bushing. You need to pick the center punch that matches your drill bushing size.
The center punch is inserted into the drill bushing and hit with a hammer to make an indentation on the cup face and help keep your drill bit from walking. The center punch is not mandatory for use but may help produce better results depending on your set up.
