I read many reviews, and I went for it. There are cheaper sets, however I liked the case design so I went with this. I used the 1-1/4" bit a lot making holes in plastic 55 gallon drums for a rain barrel project. One of the reviews mentioned that they needed a socket to remove the arbor from the hole saw bit. I hope that person hit it with his purse fist, that usually loosens them. Here is an easier way, remove the bit, loosen the grub screw, then put a smaller screw driver through the side holesSee full review
