As a DIY enthusiast, I purchased this blade to work on some of my project. However, this blade let me down on the very first use. Industrial and Scientific my foot! As a result of my tests, I determined that this blade is not durable and not worth the money. The only pro is that it was easy to install, but the con is that it doesn't last long enough to actually do any cutting. i suggest finding a different brand for your cutting needs..
Pros
Fits easily in small spaces due to compact size
Cons
The blade's durability is lower than larger blades due to its smaller size
I've made at least 100 cuts with EMT and probably 100 more with unistrut and am just starting to think about a blade change. . I can say it won't break, and I could probably use it for hundreds more cuts if I wanted to. One of the strongest and sharpest blades.
