Review on 🛠️ EONLION Mandrels: Efficient Plywood Drywall Installation Made Easy by Wayne Seba

Received today. Attempt to drill a 3" hole in a MDF laminate (IKEA). Halfway through, the mounting hole on the drill (usually oblong/rectangular) has been completely cleaned out by the force of the drilling process. No wonder, because the metal of these bits is very thin. I wasn't expecting outstanding quality for $15, but not being able to drill even a basic 3" hole in MDF is . to put it mildly. disappointing. To return.
