As an industrial and scientific user, this carbon hexagon accuracy cutting tool exceeded my expectations. As my tests showed, it cuts flawlessly and accurately without leaving any burrs. The tool is also durable and can last for a long time. The only drawback IS that it`s a bit pricey compared to other threading dies in the market. However, the quality and precision it provides make it worth the investment. Overall I highly recommend this tool for those who require accurate and precise threading work..
