These hardened teeth band blades have surpassed my expectations in both strength and durability. As my tests showed, they have the ability to cut through various materials flawlessly, all while maintaining a sharp edge. The quality of these blades is unmatched and will hold up to frequent use. However, the only downside is their higher price point compared to other Band Saw Blades. Overall, I highly recommend these blades for any industrial and scientific cutting needs.
