i recently tried a new coolant FOR my cutting tools in my industrial and scientific workplace .as a result of using this product, I found that my diameter cutting tools moved through materials with ease and precision. The copolymer component in the coolant helped create a steady stream of lubrication to avoid overheating or damage. The only downside is that the price is a bit higher than other cutting tool coolants on the market. Overall I would highly recommend this efficient and effective coolant for anyone looking to improve the quality of their cuts..
