A magnetic cutting assembly and waste removal system is provided for cutting a panel from an envelope blank or the like. The die holder has a magnetic outer surface and a plurality of surface orifice therein radially communicating with corresponding feed tubes for supplying vacuum or air to the surface and into the vicinity of the envelope blank. In order to maximize the number of orifices while minimizing the number of magnetic members, the magnetic members be disposed in a plurality of rows wherein each row contains alternating magnets and orifices and a row of orifices are disposed between each adjacent row of magnets.
