Best blade I have used for demolition I highly recommend it you get your moneys worth save time labor

Blade One!!! Best of them all!!!

Best blade for my saw I ever purchased. Demolition project at home from heavy snow load and clapsed roof. I'm cutting through a rubber roof + ridged insulation + rolled roofing asphalt + more insulation + plywood roof sheeting. Cuts through it all !!! Five Stars!!!!

It worked!

Nasty demo project, 4 roofs 2 layers of decking, incapsulated
roof over a 40 year 2nd floor addition. It wasn’t easy but no way a recip blade could have done this. Need to run it on a circular saw with balls. End result, mission accomplished.

Used the demolition blades and they’re awesome!!!!

Cutting out asphalt shingles and roof deck together

Good Blade

Purchased blade to demo a 10x12 shed. The blade worked great cutting through 2 layers of shingles and the sheeting (much better than the sawzall). I really thought the teeth would be damaged but the blade was fine and ready for next project! It was used on a old Black and Decker saw that is not a worm drive so I'm sure a better saw would have made it even smoother, but the cut went along fine. Recommended
