The optional medium duty Rocker head is a QuikSwap tool for the Evolution3. It is a general purpose cutter for materials such as banners, cardboard and foamboard up to 10mm (3/8″). The Rocker head also allows you to cut aluminium composite panel, e.g DiBond, on the Evolution3 using the Tech-D.012 blade. The ergonomic design follows the natural curvature of your hand and offers maximum comfort for every day, all day cutting. It also provides two way cutting – pulling to cut lighter weight materials and pushing for those that require more effort.
