Review on 🔩 Enhanced DEWALT DW5907 Core Body with Precision Centering by Daniel Shivashankar

These pivots ALWAYS break. I'm an experienced radon mitigator and drill at least 2.4 inches a day into concrete. Often up to 6.4 inch holes. These bits go like crazy and are never used for their intended purpose. For me they failed on the first hole and for me they lasted over 100 cores. If they don't break on the threads, they will break on the grooves. I wish there was a better product, unfortunately I have to buy them regularly to continue the business.
