As an industrial professional, I always look for high-quality cutting tool coolants. According to my experience with a particular brand, I can say that the Loc Line Coolant Component is one of the best tools that I have used so far.It keeps the cutting tool cool and extends its lifespan. The Acetal Copolymer formula makes the coolant compatible with most cutting tools. Plus it's easy to install. The only downside I noticed is that, at times, it can be a bit difficult to adjust the flow rate of the coolant..
