I got these drill bits for my husband since he needs it for his work, and also for small projects around the house. He has only used it once so far. He used size 50 to cut some hole in the wall to get the wires fished through. He said it made his job a lot easier since it was so easy to use these bits to make the hole. Prior to having these bits he used to make holes just using small bits that wasn’t for cutting the wall through. These drill bits did the hardest part which was to cut the wall and have a perfect size hole. Overall, all he is happy with this purchase I made for him. He will be using these bits more often since his job requires to cut through the wall to put wires through for installing security systems. I give it 5 out of 5 stars.
