Our recommendation: bedra EDM spools

bedra EDM wires are available on a wide range of K- and P-spools.

Our recommendation is the unique bedra spool, which has been specially developed for EDM application. Its patented shape facilitates its handling and storage. The dodecagon geometry (12-sided) prevents the spool from rolling. This allows proper horizontal storage of bedra EDM wires and increases safety at work.
