Review on 🏗️ Concrete Masonry Tungsten Carbide Plastic by Roberto Strumer

These masonry drill bits were bought as a last try for drilling tile and I hit the nail on the head! I used another brand of masonry drill bits for drilling tile and it took a very long and tedious job to use these drill bits. I was shocked when the holes were made in under a minute. Thank you for the best drill bits I have ever used. You are worth the $$!
