Dimple dies are used to improve the strength and appearance of a panel by flaring an existing hole made by a Chassis Punch in sheet metal up to 1/8" or 3mm thick.
The dies work great in a press or ironworker, and the smaller sizes can also be used with a nut & bolt on lighter steel or aluminium.
Both the Chassis Punches and Dimple Dies are made from high strength alloy steel and have a heat treatment with a unique oil impregnation to prevent corrosion, both are built to last a lifetime.
