Review on Concrete Masonry Cutters Connecting Center by Eddie Fowler

Does exactly what it's supposed to. I was able to use the largest 4.5" drill bit to drill a hole in a 12" thick brick wall in about 10-15 minutes of work. .However, there is a catch, they are cheap no matter how you look at it. Maybe 2 teeth broke off so I'm guessing he only has one hole left. BUT a single branded bit with extension would cost more than double this price and you only get 1 bit. So I think it's just a compromise.
