ASTRO-CUT MICRO XL is a heavy duty mineral oil based BIOSTABLE micro-emulsion concentrate designed
specifically to address the challenges of machining and grinding aluminum and aluminum alloys, although it may be
used to machine virtually all metals except magnesium. This chlorine-free formulation is especially suited for
aerospace and other applications which restrict the use of chlorine. ASTRO-CUT MICRO XL has exceptional foam
control for high pressure operations and was designed using raw materials that have the ability to resist extreme
biological degradation, thus providing very long sump life in a properly maintained machine tool.
