brunel xf 355

Q8 Brunel XF 355 is a high mineral oil content semi-synthetic fluid for heavy duty machining applications on ferrous and non-ferrous metals. It forms a high quality stable tight milky emulsion when mixed with water, resulting in extended fluid life and reduced fluid costs. The excellent lubricity additives provide a high quality surface finish to the machined pieces. Q8 Brunel XF 355 incorporates a highly effective anti-corrosion package, ensuring protection to machine tools and components. It is suitable for use in soft and hard water areas.

  • Q8 Brunel XF 355 is designed for heavy duty machining applications on ferrous and non-ferrous metals, it being a multi-material application product. It is especially developed for high pressure feed and speed machining on modern CNC machinery due to its low foaming capability. It is also suitable for aluminium machining including tapping application.
