Review on 🔧 3mirrors ALUMINUM Tungsten Electrode Sharpener Grinder - Efficient TIG Welding Rotary Tool with Versatile Features: Flat Grinding Block, Cut-Off Slot, Multi-Angle & Offsets, 4 Screw Holes, Dual Grind Wheels & CNC Mandrels by Jonathan Yang

I loved the simplicity of this tungsten sharpener and the number of diamond blades that come with it, but it's a little pricey for the type of components in the tool. Compared to other competing products, however, the price is acceptable if it is held for a long time. So far I've been using it for a few weeks and everything is fine. I purchased an additional diamond blade from another Revain supplier as I expect the blade to wear out fairly quickly given the hardness of tungsten and the very thin nature of the blades. A few additional notes: The brass inserts are very tight which keeps the angle very accurate, but if the tungsten oxidizes and needs resharpening the electrode can be difficult to insert and you are limited to only one degree of angle of each size. made of tungsten. I have to admit that my reservations about the price are allayed by the very convenient access to resharpening that this tool offers. I keep it next to my welding table and can resharpen without getting up.
