中心定位模具

Punching a hole first and then centering the washer used to take me three tries to get concentric. These drop right into my cutter and line up dead center on the first punch, no eyeballing. My stack of brass washers finally looks uniform.

Wasn't sure these would line up right but they drop into my cutter with zero fuss. Punched a few test washers and every hole came out dead center on the first try. Makes stacking discs so much cleaner.

These fit my existing disc cutter perfectly, no wobble at all when I set them in. Punching a hole first and then centering it means my washers actually come out concentric now instead of slightly off. Took a couple tries to get the hang of the order, but the results are dead-on.
