After I put it to the test, I can say that this slotting cutter is not worth the investment. It was unable to cut through the materials I needed to use it on, making my job much more difficult. Despite its claims of being a powerful cutting tool, it fell short in its performance. The only positive aspect is its size, but it's not enough to justify purchasing this product. As someone who frequently uses cutting tools for industrial and scientific purposes, I would not recommend this cutter chain
