As an industrial and scientific professional, I highly recommend these bi-metal blades cutting tools. As a result of my tests, I determined that these blades are strong, durable and have excellent cutting capacity. The blades cut through hardwood with ease and make smooth cuts every time. Plus, they last much longer than other band saw blades I've used in the past. However, the only con I can think of is that they are a bit pricier compared to other options on the market. But in my opinion, the quality and longevity make them worth the investment.
