This dieset is designed for use in either the HD6500 or the HD7000 Punch. The Rhino HD6500 and the HD7000 punches are both 14" open-ended punches and are capable of punching up to 40 sheets of 20# bond paper. The HD7000 uses the Rhin-O-Tuff patented quick change die system while the HD6500 uses a two bolt EZ change slide out die system for changing punch patterns.
