Thanks to my knowledge gained in practice, I can tell you that this hole saw is perfect for cutting through thick metal sheets without leaving burrs or reducing the blade life. The carbide tip stays sharp even after multiple uses, cutting with precision and causing very little vibration. One disadvantage is that the mandrel seems weak considering how solid the blade is, but it can be replaced. Overall, worth the money for cutting circular holes efficiently.
