We purchased a used EDM machine and it came with a cabinet with over 180 system 3R 20mm holders and storage racks. Does anyone use these anymore? We'd be willing to sell them if anybody is interested.
Everyone says to sell these on e-Bay and you can for the time and trouble it might take (never done it, so I don't know).
With much to pay-back, I donated most of the 20mm holders from my shop (mounted and unmounted) to several schools where they were used for EDM learning-and-burning.
Depending upon your state, you may also claim an itemized tax-deduction for its valuation.
