I recently purchased a copolymer coolant for my cutting tools and have found it to be extremely efficient in keeping the tools cool and preventing damage. As my tests showed, using this coolant increased the lifespan of my cutting tools and improved THE quality of the cuts. This product is a great investment for anyone looking to improve their industrial and scientific cutting processes. The only downside is that it can be a bit messy to work with.Overall, a fantastic product that I highly recommend!
