This blade failed to meet my expectations for industrial and scientific use. While it did have decent cutting power the blade seemed to dull quickly and became a hassle to constantly replace. Only positive WAS the initial cutting strength... Overall, this blade was not worth the investment for me due to frequent replacement..
These blades break well before the teeth dull, very disappointing. There are no cracks in the welds. When they run out, I'll try the custom Fastenal blades.
