GET DEMO DONE.

Love these Blades for cutting through old Roofs to set HVAC Curbs! I bought this pack not because I need them (cause these blades really last so I still have 3 new ones from my last pack) but because I was afraid something may happen and I couldn't get them when I do need them. Hot Knife Through Butter I Say, with NO Gumming Up The Saw, I still can't believe it and I was the one using it!
Every HVAC & Roofing Supply House Should Have These Blades!

Used this blade to saw through three layers of shingles plus 3/4" plywood. The 5T cut through with ease and no binding. Only used one blade for half of the house, will finish second half later. The 5T is still sharp and cuts like a new one. I highly recommend the 5T to anyone who is working on a demo roof job. It will definitely save you time and money and will not drain your muscle power. Works really well on a 71/4" circular saw.

I am in the Hvac industry and have been needing these for years. I was fixing to buy a 1300 roof cutting machine when I came across these. The job I was on was burning up 2 regular framing blades per curb (roughly 22’ or so as this was the thickest roof I’ve ever seen in 25 years). I ordered this blade on Friday night and had the dang thing Monday. I took it to the same job on Tuesday and it was like a hot knife through butter. When I got through with my job the roofers (finally showed to take off the rest of the roof) ask to borrow it and they used the same blade all day and it never gummed up the first tine for either of us! I ordered the contractor pack As soon as I got home!

we tried every blade out there.. also tried making 3 passes with increasing depth.. we ended up with a 2 man operation one on the saw and one spraying wd40 to help reduce the tar buildup... this little medieval looking blade is scary looking, it aint meant for the faint hearted, but it made the process 5x faster, saved cases of wd, numerous blades, and went to a 1 man process.. roughly equivalent to, a >90% labor and material savings on this portion of work

The only blade that would work on a 1-¹/² 2 layer nail embedded subfloor demo job Diablo Demo Demon blades lasted 5' of and were spent, Lenox lasted 15' . I thought that's not good these blades suck I need a serious Demo blade, searched online found the Big Blue order 4, cut for an hour ordered 4 more! Must have a worm drive!

I did roofing all my life and we would have to cut though the peeked and we went through saw blades by the hundreds I bought this blade and I cut though 2 layers of shingles and the plywood it took me about 5 minutes to cut though it all very happy it’s a 10 star

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

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!!!!

At first look you would think it's one of those tools that is not really going to perform like people say it does. I cut two layers of shingles and 3/4" plywood 1 1/2" Total in one smooth cut ! No one has mentioned it also cuts much wider than a standard blade. This allowed us to fit different types of prying bars to lift the sections. Blade paid for it self and saved us about $250.00 on first job.

I wish I would have found out about this blade years ago! Cut through two layers of shingles, metal drip edge and into the roof sheeting with ease, Worth every penny!

I used the BigBlue 5T blade for dismantling a collapsed roof over my deck. It worked like a charm and I had that roof in stacked up pieces in much less time than I imagined I could. It made an easy job out of what I thought would be a time consuming pain in the but. Very Happy!

I put it on a cheap Ryobi saw and it just zips through old build up roof when cutting about 3/4" deep

I have been in the carpentry / reno business for over 30 years and I am a hands on working owner. I will say this is the best demo blade I have used. Thanks for a good blade.

I used this blade to cut through 2 layers of shingles on 5/8 plywood. It worked perfect, all day long. I could have done many more jobs. Well worth the price.

Works great. Ripped through 2-layers of asphalt shingles like a hot knife through butter! Can't get any better than this blade.

Effortlessly cut through 5 layers of asphalt shingles, wood and nails without throwing debris all over me.

Great addition to the job at hand, cuts work time in half

These blades are awesome they just keep cutting perfect demolition blade easy to control and cuts super fast. Will not buy any other brand of blade for demolition again.

Wouldn't have thought there was a tool that could cut through 3 layers of shingles plus plywood sheathing plus aluminum flashing and the occasional roofing nail. But this blade danced through that stuff like it was a hot knife in butter. Initially tried an aggressive blade in my sawzall. All that happened was a gummed up blade.
For demolition, I don't think there is anything better than a BigBlue 3T.

We took out an old roof by cutting it in big pieces. And it cut very well through asphalt shingles with OSB and 1 row of planks. Very impressed

This blade was exactly what we needed. We cut several hundred lineal feet of 2-3 layer torch-down plus 5/8" CDX deck with the 5T blade, no problem. My roofer saw the setup and stole my backup blade, smart guy.
