A vacuum assist anvil cutting die set includes a cutting cylinder and an anvil cylinder. The cutting cylinder has an outer diameter surface with a cutting blade and a blade cavity adjacent to the cutting blade. The cutting cylinder has a vacuum port in communication with the blade cavity and is adapted and configured to be connected to a vacuum source to apply a vacuum to the blade cavity via the vacuum port. The anvil cylinder has an outer diameter surface with an anvil pin projecting from the outer diameter surface of the anvil cylinder. The anvil pin having a diameter and shape that closely approximates the blade cavity such that when a level of vacuum is applied to the cutting cylinder and the anvil cylinder is in rotational and linear register with the cutting cylinder, the anvil pin is insertable into the corresponding blade cavity in a manner to increase the level of vacuum of the blade cavity.
