A drum cutting device, e.g., for shears adapted to cut flat metal products advancing along a direction substantially parallel to their direction of longitudinal extension, said device being adapted to cut said flat metal products transversely relative to their direction of advancement, wherein said device comprises at least one drum adapted to be rotated and diametrically delimited by a cylindrical surface containing a blade or knife which partially protrudes from said cylindrical surface, wherein said blade or knife is partially housed in a seat of said drum and extends longitudinally along a direction substantially parallel to the rotation axis of said drum, wherein said device comprises an adjustment wedge also housed at least partially in said seat of said drum, wherein the direction of extension of said wedge is substantially parallel to the rotation axis of said drum and the thickness of said wedge transversely to its direction of extension varies continuously along said direction of extension from a minimum thickness to a maximum thickness, wherein said wedge is positioned relative to said blade or knife so that the translation of said wedge parallel to its direction of extension in a first direction of translation results in a peripheral tangential translation of said blade or knife in a first direction of peripheral tangential translation, while the translation of said wedge in a second direction of translation opposite to the first one results in the peripheral tangential translation of said blade or knife in a second direction of peripheral tangential translation opposite to the first one, said device comprising translation means for the translation of said wedge in said two opposite directions of translation.
