Review on 🔧 Cutting-Edge Concrete Masonry Tools: Plastic Tungsten Carbide Innovations by Jason Staggs

Very good drill for cutting holes in tiles. I used them to conduct electricity between floors through porcelain stoneware. They have performed as advertised and have enough lifespan for future use. I have a small "chipped off" top of the tile, but I believe the problem was user error rather than just a bug.
