Greenlee (Rockford, IL) and Challenger Tool are 2 well known suppliers for D-subminiature punches. http://www.stanleysupplyservices.com/challenge-tool-panel-punches-for-d-subminiature-connector/g/1273
After the 2008 Wall Street crash, I picked up a used DE-9 punch for around $100, that us about the cheapest you will see them used. DB-25 may be a bit cheaper as used, but I set a purchase limit of $200 fir these Greenlee or other punches. -- You received this message because you are subscribed to the Google Groups "N8VEM-S100" group.
