Unbeatable only things I haven't tried it on are glass and tile, but wood, metal and concrete are usually what I deal with and I throw out screw/anchor kit bits away I only use these for going on a year now

Good quality masonry bit. But, it won't cut porcelain, glass tile, or metal. And they do wear out. I gave the product three stars because of the hype and overstated longevity.

To be honest I was afraid that I had wasted my money, but the bits have done everything as advertised. Drilled a 1/4" hole in a wall tile as smooth as a baby's hind end. Thinkin about Christmas gifts for my sons and son in law.
