## Customer Reviews

### ⭐⭐⭐⭐⭐ Good blade!
*by B***N on June 5, 2025*

I use this as a power chisel and it works well.

### ⭐⭐⭐⭐⭐ cuts roofing shingles fast, durable
*by M***R on May 30, 2024*

I needed to recut a roof/wall intersection in some old architectural shingles. Two roof/wall transitions, I did the first one with a simple saw blade in the oscillating tool. It took a while and I worried a little that I would cut the step flashing (though it's galvanized). All of the teeth were worn off on the first shingle and cutting 10' of valley took 1/2" off length of the blade. That wall took an hour or so.So, I bought this blade for the other side. Wow, 10x as fast. Slices right through the shingles, asphalt, fiberglass and sand. I did pretty good at lifting just as I came to the bottom of each step (cutting up - trust me) but when I did catch a step, this blade would not cut it at all. I'm confident that I did not damage the flashing in this little adventure. Got that side cut in 10 minutes. The blade appears to have not worn down at all.I also tried this blade on some cardboard since it says it's for 'soft materials'. Cuts cardboard like buttah.I will say though - you want to know where your fingers are when using this particular blade.

### ⭐⭐⭐⭐⭐ Get.s it done
*by D***N on December 23, 2024*

worked great on acrylic caulk without tub or tile damage.
