Review on 🔨 Drilax Diamond Concrete Masonry Cutting Tools: Industrial Drill Bits for Precision and Efficiency by Michael Gonzales

I bought this item because I couldn't find it at my local hardware store to drill holes for plumbing going through the hollow concrete block wall in my house. Backyard. After successfully drilling three holes and partially through the fourth, about half of the "teeth" broke off. I couldn't continue and had to hope it went far enough to tap on it with a hammer to finish the job without destroying the whole block. This article is now in the trash where it rightly belongs!
