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 John Campos

It's really good with the smaller tungsten, although a little underpowered for a 3/32. much faster at 3/32 with a diamond wheel and drill bit. There are a couple of flaws that caught my eye straight away, there is some play in the holes which causes the tungsten to skew slightly when you turn it by hand and the diamond wheel bends a little making it difficult to sharpen evenly across the entire blade Scope but I just sharpened 3 x 10 packs of tungsten in about 15 minutes and am happy with the results.
