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 Tres Carmon

This product is perfect for my needs as I have my own tungsten sharpener. Welders can get a little nervous sharing a grinding wheel so this product gives me more confidence and saves me time by avoiding unnecessary trips to the grinding wheel. The aluminum body is thick enough to withstand a fall. The corner rails are interchangeable so corners can be easily adjusted. As long as you read the instructions that came with the product and DO NOT MIX the TUNGSTEN ON THE DISC, they will last quite a long time. I use 1/8" gold for TIG welding aluminum and have not had to change the diamond blade yet. Let someone else complain about the grooves on the grinding wheel and get consistent advice every time!
