Tool and mould making: Our carbide blocks offer the precision and reliability needed for the production of tools and moulds.
EDM blocks
We supply high-quality eroding blocks or also called electrical discharge machining blocks that have been specially developed for precise eroding processes. Our EDM blocks are the ideal choice for numerous applications in the tool and mould making industry as well as in metal processing. Discover the advantages and special properties of our EDM blocks.
Our range of EDM blocks
With the new tungsten carbide EDM blocks, Graf Hartmetall presents a perfect combination of wear resistance and fracture toughness. These properties make them particularly suitable for a wide range of applications such as punching, embossing, bending and forming.
Our high-quality carbide grades guarantee a long tool life, maximum wear resistance and outstanding edge stability. The carefully selected fine and medium grain grades of the EDM blocks offer a balanced material that enables the reliable machining of complex and delicate tool geometries. Thanks to their high corrosion resistance, the EDM blocks are ideally suited for wire electrical discharge. They also optimally meet the mechanical and physical requirements of toolmaking.
Graf Hartmetall offers a wide range of sizes of EDM blocks to customer specifications, which minimises waste and keeps costs as low as possible.
