Review on 3mirrors ALUMINUM TIG Welding Tool with Tungsten Electrode Sharpener Grinder Head, 24 Guides 🔧 Including Dust Housing, Cut-Off Slot, Multi-Angle & Offsets, 5 Diamond Wheels, and 2 CNC Mandrels by Rick Rogers

waste of time and money. The mandrel included in the kit is too long and only allows the use of a pilot hole. The rest is too low and the tungsten doesn't even touch the grinder. The only hole you can really use is moving the scratches the wrong way. I've been trying to figure out how to get it to work properly for hours. Gave up, sent it back and bought a 150 grit carbide stone for my bench grinder.
