Diamond Ground Products produces the highest quality pre-ground tungsten electrodes on the market. We also are able to take your used tungsten electrodes and re-grind them to the exact same tolerances which we start from scratch. We call this our Re-Ground Tungsten Electrode Service. Send us your spent tungsten welding electrodes and DGP will regrind them to meet or exceed the tolerances and finish required. Re-ground tungsten electrodes save you time and money and are available in 3 days or less turn around.
