It's Time to Make the Switch to Top Performing DS4 Ultra-Fine EDM Graphite

“Our detailed engraving of molds and stamping dies demands an EDM electrode that provides excellent durability and delivers sharp corners and fine quality. We switched from the leading ultra-fine EDM graphite to Mersen's DS4 and it really performs … and saved us money. ”
