Review on Ultimate Carbide 🛠️ Masonry Concrete Ceramic Solution by Matt Jenkins

I used these bits to drill mortar between the bricks above our chimney to make holes for nails to hang a heavy picture. I didn't measure the bits when they arrived to make sure the length was as advertised, but I could use a slightly longer bit. I'm glad I got a few bits because they dulled quickly. I used at least 4 to complete the bore.
