Review on Sabre Tools 4-Piece Carbide Concrete Cutting Kit by Mayrando Clark

I bought these not expecting them to last as the price was too good for more than a few uses. I used them to drill through extremely hard natural granite to secure some of the deck posts. Everything went quickly and easily the first time. The 2nd time wasn't as good as the 1st and the 3rd still worked but took about 2x as long as the first time. Projects like this only happen to me every few years, so the purchase really met my expectations for the price.
