Review on 3mirrors ALUMINUM Tungsten Electrode Sharpener Grinder Head - Efficient TIG Welding Tool with Cut-Off Slot, Multi-Angle & Offsets, 4 Copper Screw Holes, 1X CNC Mandrel & 5X 25mm Diamond Wheels by Hals Martin

Another professional welder that does side jobs outside of my home workshop looks like good value for money but it isn't. The main problem is that he uses the very edge of the wheel to sharpen the tungsten. When not forced to stay on the wheel, it sharpens tungsten with an off-center tip. Unfortunately, if you get a good tip, if it's that far from the edge of the wheel, you'll end up with a twisted grind. Sample. The same as in the description you want to avoid.
