Review on Plastic Drilling 🔩 Mandrels Installation by COMOWARE by Brian Cooper

I needed to install a split air conditioner clamp and needed a 3.25 inch hole saw. This set was a little more expensive than the big brands but you got a lot more sizes than the premium brands. It barely did its job and took a very long time. The inside of the case smelled very bad and was oily. I probably won't need to use it anymore. right size and don't worry. Do not choose this brand for many jobs and sizes. For casual use, this brand might suit you.
