Review on 🔧 High-Performance JIUWU Carbide Cutter for Concrete Connections by Lakeem Pickel

I used this on a 10" concrete wall and the hole saw could only go about 8" before half of the carbide teeth were completely worn out. I also used water for continuous cooling. I think this saw might only be good for softer material like cinder block or brick. I was expecting to be able to cut at least 1 hole but figured it would be enough for 3. I was wrong. I used a smaller hole saw to continue the work and came across rebar. He couldn't cut through the rebar at all.
