Blended with high-tech special additives and high quality special base oils, it has been developed for heavy duty operations such as cutting, surface treatment, and particularly deep hole drilling of all kinds of hard steels. It can be safely used as cutting and cooling fluid for drilling and chip removal of various types of steels, including special alloy steels. Thanks to the high pressure additive in its content, it helps the formation of excellent surface quality by facilitating cutting and drilling operations at different process speeds and large size chip removals. Since it is suitable for operation at high speeds, it contributes to increasing process efficiency and extending the life of the metal processing equipment used. The same high pressure additive in its content may also cause staining on copper and alloyed yellow metals.
