Deals: A Free Trial Tungsten Grinder Wheel from Diamond Ground

If you operate a larger welding shop, you probably grind your own tungsten electrodes. And, if you happen to own a Sharpshooter or Turbo-4 electrode grinder, Diamond Ground Products would like to give you a free grinding wheel to encourage you to try their product line.
According to their press release, they’ll also offer you direct prices at “up to 50% off OEM manufacturer prices” on future replacement wheels, and they’ll give you cash for your current (other-manufacturer) grinder if you wish to trade it in on one of their models.
