EDM 3R System Electrode Holder Machinist Tools moldmaking grinding fixture

Description

I am putting up for sale several EDM tool/electrode holders. I purchased or made these holders a long time ago. I used them only a few times for work. Many years ago I switched from using the 3R System to the EROWA System. I placed the fixtures into shelf storage after covering them with corrosion protection in case I needed to use them again. The need to use them again did not arise. I see no need for them in the future either. I have decided to sell them. P
lease see my other listings for similar items.
