To sharpen tungsten electrodes, I purchased an inexpensive bench grinder and a 1/4" reversible electric drill with a keyless chuck.
Turn grinder on, chuck up a tungsten and grind lengthwise,reverse drill & unchuck. I can prepare at least 12 on both ends in less than 5 minutes. Saves a lot of time going back and forth to grinder especially if you are on production or working out in the field.
Grinder is for tungstons only.
Tip from old RON--Have a nice day.
