Review on 🔩 Efficiently Countersink Screws with ABN's 5-Piece 82 Degree Screw Countersink Set by John Pound

I only got these to countersink some screw holes in the underside of the graphite chassis of a vintage RC car. It was a bit delicate work and they did a great job. My rating is solely based on this usage as I have not used it for anything else. Well made and sharp enough, they did exactly what I needed to this point.
