Abstract
A water-soluble cutting fluid which is characterized by excellent cooling and lubricating properties and does not exert a harmful influence on the environment. A solution containing hydrogencarbonate ion, bromide ion, carbonic acid ion, and, if necessary, fluoride ion, and being adjusted to a pH of 7.0 to 11.5 can be used as a substitute for a cutting oil. A water-soluble cutting fluid further including additives such as rust-preventive agents and the like can be also used as a substitute for conventional cutting oil.
