Review on 🔧 High-Performance JIUWU Carbide Cutter for Concrete Connections by Jump Robinson

I used my set for the first time today and it eats red bricks well. Cement blocks are no problem at all. the floor filled with cement whimpered a bit at first, but after 2 inches the last 4 inches were fine, the only negative! It's a set screw on the side. it didn't stay taut and the centering jet came loose and vibrated. My solution was to get an extended class 8 set screw and put it in, then use a class 8 nut to tighten it, voila, no more problems :D
