RIVOLTA S.KS.48 is a fully synthetic special cutting-oil for most difficult machining operations. To afully synthetic base oil we added extreme pressure additives and anti-wear agents which increase the compressive strength of the oil and which improve the surface properties of the machined workpieces. Therewith one can even machine economically highalloy steel in most difficult cutting processes.Long tool lifes and an optimum quality of the workpieces are the result of the application of S.K.S.48.
