Did the trick

Just finished cutting wider gaps in deck, 2x6's. 832 lineal feet. Unfortunately it burned out my Skill 2 3/4 horse side winder saw (made in America). This blade has a lot of bite. That is not necessary a bad thing. I rented a worm gear Bosch and it worked perfectly. I also included a temporary Lounsbury Guide plate to follow grooves. This is a kick butt blade, so use a kick butt saw.

Right tool for the job

Worked as needed, clean cuts and durable for cutting the spacing between my composite deck boards.

BigBlue needs a resharpen

The blade looked awesome and it cuts as advertised. My problem was I cut in to a valley that had a galvanized valley under the shingles that I did not know was there.
