EDM Graphite Blocks, 6” x 12” x 3” +, EDM Sinker, Graphite

Description

EDM Graphite Blocks, 6” x 12” x 3” +, EDM Sinker, Graphite.
Material As per photos.
Some of these blocks may have a few small chip outs along a few edges. Not a big deal but I did want to state that. If that is an issue please let me know and I will make sure you get a good one with no chips at all.
I picked these up at a large machine shop auction. They had EDM sinker machines on site and were using this material for the electrodes.
Not sure of any exact grade but as stated above they were using for their EDM machines.
Thanks
John
