Semi-synthetic machining and grinding fluids are synthetic-based coolants that typically contain some oil for added lubricity and corrosion protection. This makes them ideal for light-to-moderate machining and grinding applications. Semi-synthetic coolants also offer many of the same advantages as synthetics.
