These are premium quality water soluble cutting oils, specially developed to form extremely stable milky emulsion even with extreme hard water (400 ppm) leading to excellent tool life and finish, in all metal cutting operations, where cooling is more important than lubrication. They have excellent antirust and anti-froth quality and cause no corrosion of machine, work piece or tool. They do not decompose chemically; leave objectionable odour, cause discoluration and staining. These are operator friendly and economical in use.
PALKUT - SL is blended from refined mineral oil, emulsifier and other additives.
Recommended for cutting, drilling, shaping, grinding, and other metal removal operations of ferrous and non ferrous materials where high quality of coolant is required. Not recommended for the machining of Magnesium due to potential fire hazards.
