So nice to have a designated grinder for tungsten now, and I don't have to walk across the shop everytime I need to sharpen up. Couldn't be any easier to use and the bundle pack is a great value. Highly recommended! Thanks Tony Naghiu

This is a replacement for the our first one that lasted 6 years under heavy use. The electrodes weld so much better when sharpening them accurately with this dedicated tungsten grinder over using a belt sander or grinding wheel as was used previously. It is much quicker to use and you will grind away less tungsten than the other methods. If you have not tried one, go ahead and buy it, you will be glad you did.
