BigBlue 5T worked great!

I demoed an entire roof cutting through 3/4" boards, an overlay of 1/2" O.S.B, and the roofing shingles all at the same time (nails and all) and I didn't even have to sharpen the blade once. The best part was that when cutting through the roofing material it didn't produce a lot of powdery sawdust that is normally such a nuisance. The cut material was more the size of grains of rice which was very easy to manage. The overall quality of your product is every bit as good as your product's claims.

It's good to see that some companies still believe in producing "quality" products that can be relied on at the job-site.

5 tooth blade

cut through 50 year old roof boards with 2 layers of asphalt shingles like cutting 3/4 plywood. took roof off 21/2 car garage and blade could keep going(sharp). throws chips like cutting with chain saw.


Excellent tool. Bought 2. Job is done & still have 1 brand new & unwrapped. Highly recommend.

5T Demolition Blade

Worked as stated and cut through everything in its way. I actually thought it would make it through my entire roof ripping needs of (4) full length rips 44.5 ft. long through fiberglass shingles roofing nails & sheathing, but it needed to be sharpened after (2) 44.5 ft. long rips.

Leroy, that is not the performance we would expect from BigBlue 5T when cutting through fiberglass shingles, roofing nails, and sheathing. We'd love to connect to see if we can diagnose the problem. We'll reach out to you shortly.
