This is a row of tools set up on a bed plate for use in a press brake - where a row of holes are required along the edges of extruded plastic ducting. As well as front loading to punch the edges, the
tools have been designed to punch the row of holes between the extrusion divisions in the cross section. To do this the tools have pedestal finger dies and sleeves which extend down below the upper leg of the
C-Frame units (Model M10PF types). The component has to be end loaded and fed through the tools to be able to punch the inner rows of holes.
