This cutting TOOL is a must-have for all industrial and scientific applications. Based on my observations, the tool is highly efficient at deburring external chamfers on stainless silver surfaces, which saves a lot of time and effort... The 2-Pack option ensures that you have a backup tool in case of damage. The only con i noticed was that the tool makes a lot of noise but this is expected with such a high-powered industrial tool. Overall, a great investment..
