Review on 🔧 Rannb 3-Inch Pipe Drill Opener Plate by Rodney Gonzalez

The spring pushes out most notches. Slots allow you to remove the ones that just don't show up. Hex bits work well. In addition to inch sizes, you have a pretty good selection of different sized holes in metal and plastic. I prefer Forstener bits for wood and some plastics. that drilling a small diameter hole facilitates chip evacuation and speeds up drilling.
