Review on QWORK Hybrid Concrete Plastic Tungsten by Charles Lardieri

I used these bits once. For four holes, see picture. After/during the 2nd hole the bit broke and I had to switch to a larger bit to finish the holes for my TV mount After the 4th hole the big cutter looks horrible and I'm sure if I use it for something else, he will break. I read the reviews and some of them were the same as now but they didn't mention for professional work I just mounted a TV so yeah let's give it a try. It is not for professional or any other purpose. I'm just thankful that I was able to finish all four holes and not have to go to Home Depot to finish that. Don't waste your time and money!
