As a professional who has been working in the Industrial and Scientific field for many years, I was excited to try this hole saw for my latest project. However, I was sorely disappointed with its performance. Thanks to my knowledge gained in practice, I know that the saw's triangular shape was supposed to ensure a clean and precise cut, but instead it barely cut through the material and left rough edges. The only positive aspect was the stainless-steel material, which seemed to hold up well. Overall, I would not recommend this product to anyone looking for a reliable hole saw option.
