Extra-wide Kerf Circular Saw Blade
At just under 1/4 inch, BigBlue™ has the widest kerf available on a 7-1/4 inch circular saw blade.
No-Clog Design
Gullets this large never clog... ever. Open space reduces friction and keeps the blade spinning fast. This empowers circular saws and worm drive saws to cut tough construction materials not possible with other blades.

Built up roof removal
I have a built up roof with 3/4" plywood that I used this blade on. It worked very good and cut both the 2" tar and gravel and the plywood at the same time. I tried other blades and means to cut the roof but this was the answer. It worked great and did not gum up at all. I made a total of 660' of travel and it was still sharp and cutting well upon completion of the job. I would purchase again and try the 5 blade if I needed to do something like this again. I am not a roofer.

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

Beast of a tool
While adding a ceiling fan into a room that was added-on to the house decades prior I discovered what I thought would be an attic with exposed ceiling joists was in actuality an old tar/pitch flat top roof. This old tar roof possibly had leaks and since had a sloped roof added above.
I found this tool on an internet search and the price was right for a blade I had never seen nor a brand I was familiar with. Blade arrived promptly and the next day I plunge cut 4 access holes into the old tar/pitch roof. This was a champ of a tool and has many more cuts left in its life.
