A sheet metal forming tool is designed to remove raised eyebrows surrounding dents in the body of a vehicle before the dent itself is pulled back to a flush configuration. The tool comprises a pneumatic hammer driver provided with a special attachment having a body and a plastic head. The head is formed of plastic and is configured to define a ring-shaped support base that surrounds a dome-shaped hammer pad. A hammer within the tool impacts the back of the hammer pad at a frequency of between 2000 and 5000 impacts per minute, each impact moving the hammer pad slightly outwardly with respect to the plane of the support base. In use, the head is placed over an eyebrow to be treated with the support base resting on the surface surrounding the eyebrow and the hammer pad overlying the eyebrow. The tool is then actuated and moved along the eyebrow until it is bent back down flush with the surrounding surface.
