The right dielectric for every machine!

Whether for roughing work or use in ultra-fine finishing – the dielectric has to satisfy the very specific requirements for every application. The high-performance dielectrics from oelheld are made from synthetic base oils and contain discharge-intensifying and wear-reducing additives and ageing inhibitors for use in electrical discharge machines (EDM).

By contrast with the conventional mineral oil products, the high-purity synthesis products enriched with the oelheld-patented satellite electrodes from the IonoPlus series are manufactured in a special blending process.

It does not matter whether die sinking, wire cutting or start hole drilling, we have the right dielectric for your machining process!

In our brochure you will find all information about our dielectrics, the longstanding development as well as the advantages of the products.
