Review on 🔧 Rannb 3-Inch Pipe Drill Opener Plate by Athenasby Whitney

I bought these to install some buttons for an arcade setup that were metric. They are true to size. I used them on MDF. They burned firewood very badly. I don't mind this as I will be putting buttons through the holes, but this may not work for everyone. They also "blown out" the back of the hole. I tried to be very careful when I got to the end, but the top layer of wood came loose about 1-2 inches around the hole as it worked its way to the back of the hole. It didn't make much of a difference in my application, but it might break some people's projects.
