The Steck Panel Shaper Kit (20046) is an air-hammer-driven set that consists of three self-lubricating nylon-reinforced heads that allow technicians to reach deep areas and bring deformed parts back to their original shape.
Each kit contains three unique nylon head shapes with arbors. This allows each tool to be attached to your air hammer to fix body lines, concave areas and at surfaces. Unlike traditional hammer repair, the Panel Shaper saves technician arm fatigue and hours of repair time.
