Just as advertised

My Carpenter was a little apprehensive when I gave him the blade to use. He is not now and is sold on the product. It worked great cut through plywood decking and asphalt shingles with no problem.

Cuts well

Our foremen have mixed reviews of this product. We don't use it in a rip cart but in a hand held saw. The guards tended to gum up with roofing material, but after Brenden suggested spraying the guards with silicone spray the cleanup was much easier. Some guys love the blade others not so much because of the cleanup issue.

Great demolition tool

I used this blade to cut a garage roof into pieces to tear it off to redo the trusses. The blade worked awesome it cut through one layer of shingles tar paper 1/2 in OSB and original 1-in pine boards. we used a worm drive skill saw which I think is a necessity I am pretty sure a regular skill saw would not have had enough guts to power the blade. we cut the roof into 3-ft square pieces peeled it off through it in the dumpster less than a half a day's project. one suggestion I would make is to make sure when you're cutting across the roof that you try to cut where the roofing nails are not every so often it would pull a nail out and jam it between the blade and the blade guard on the saw. But once I figured out what was going on I did not have another problem with it. Would recommend this blade to anyone.
