These things rip

Cuts like butter threw 2 layers of asphalt shingles, 1/2 plywood and 3/4 inch barn board. Lasted the whole day. I needed up buying a 4 pack after I bought the 1 as a trial blade.

André (Seattle, WA)
As advertised but hard on the saw

It does what it says and rips through whatever is in front of it. Using a mag77 saw and trying to cut through roofing and sheeting like I would with a thin kerf blade smoked the brushes on my saw in less than 10 minutes. Chalking this up to user error but you have to go slower than you might think with the huge teeth.

Aaron Saxton

I had a flat roof with bitumen build up and a base layer and the blades tore through it, including nails and drip edge. Without these blades we would have had to have purchased or rented a roof cutter. Instead, this blade with a powerful circular saw ate the roof in record time. Having the blade on a circular saw allowed us to get a precise depth also to avoid the decking below. The blades are beasts and we did over 250 linear feet with the blade and it is still cutting.
