Review on 7-Piece SUNGATOR Hole Saw Kit With Arbor And Allen Key - Perfect For Wood, Plastic, PVC And Drywall by Stephen Cernatescu

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 holes and remove the hole saw bit. Not hard right? That is because its not hard! Are there better bit locking designs? Yes, in this kit when you use the larger arbor its an easier design to remove it. Some reviews you need to understand the author's skill level.
