EP770 – Grinding fluid

Our grinding fluid has been specifically developed for our wet grinders – Ultima-TIG, Ultima-TIG-Cut, Ultima-TIG- S and Neutra. It cools and lubricates the grinding process to ensure optimal grinding conditions.


  • Protects against corrosion of all components in the grinding chamber.
  • Has a cooling effect on both the diamond disc and electrode during grinding operations.
  • Gives enhanced results with more finely ground surface of the electrode.
  • Has long life due to preservatives in the grinding fluid.


Quality grinding of Tungsten electrodes

In order to ensure optimum utilisation and protection of our wet grinders – Ultima-TIG, Ultima-TIG-Cut and Neutra – it is important to use the original grinding fluid, EP770. It is also crucial that there is sufficient grinding fluid in the grinding chamber. Without this fluid, or if the fluid level is too low in the grinding chamber, the electrode and the grinder itself will quickly get too hot.

Ordinary tap water is not a viable alternative, as this will result in corrosion of the components in the grinding chamber. Moreover, water does not have the same lubricating and cooling effect as grinding fluid – which will result in lower quality in terms of grinding. Other grinding fluids generally provide poorer protection against corrosion – and may result in both the fluid and the dust sticking to the grinding disc, thus causing it to lose its grinding capacity.

The original grinding fluid

The combination of liquid for cooling and a high grinding speed of the diamond disc results in a polished and even surface of the Tungsten electrode. In addition, the cool wet grinding shortens the grinding time and prevents overheated and damaged electrodes.

The grinding fluid contains:

  • Grinding coolant
  • Color
  • Preservative
  • Water

Disposal of used grinding fluid must always be carried out in accordance with local legislation. As there are residues of grinding dust in the used fluid, information on the electrode data sheet concerning the disposal of electrode residues must be taken into account. Ask the supplier for the data sheet, if required. Disposal of clean grinding fluid should take place with other oleaginous chemicals.
