Use the Planishing hammer to your advantage – Penn Tool Co

Planishing hammers are air-powered metal shaping tools that stretch or smooth metal by striking it with dies on both sides. An efficient planishing hammer has the advantage of being able to work in tight locations and on a specific section of the panel. The bottom dies in steel and aluminium can be swapped out to get different radius shapes. It has a pressure regulator and an in-line oiler.
