Efficiency. Precision. Process security.

High speed with long service life

Our erosion material is substantially more resistant against abrasive wear than conventional electrodes made from copper/brass. Therefore, the consumption rate of the contact material is lowered and, in turn, the tool life is lengthened enabling higher possible feed rates.

Precise grinding for successful erosion

Success factors are exact positioning accuracy and minimal run-out during the erosion process, particularly with small diameters and deep holes. Automatically inserting electrodes happens seamlessly thanks to the precise polish grinding and h6 tolerances.

Carbide properties:

- Wear-resistant

- Rigid, solid, and accurately positioned

- Possible to cut to size without burrs - as a result, deviations on the form, which is to be eroded, can be excluded and the burr does not have to be removed manually.


Our high-quality erosion material is used successfully in every industry that requires extremely precise holes.
