Review on Plastic Drilling 🔩 Mandrels Installation by COMOWARE by Darius Carraway

I used them to cut a few holes in OSB and plywood. Hole saws worked best in plywood. When the saw turned, there was a lot of smoke in the OSB. It seemed like I hadn't stopped the saw, the OSB would have caught fire from the heat of the spinning saw. So I stopped the saw often while working my way through the board to keep the smoke to a minimum. Overall there is a perfect range of saw blade sizes and they are easy to use. These hole saws do their job well and are great value for money.
