have to pay more for just another hole???

If you're just starting out with TIG welding, no doubt, you'll be sharpening electrodes. And the Piranha does the job. Far better and I think safer than throwing tungsten dust all over the place as well as producing points that can be more or less blunt depending on need. It's expensive and you probably can do with one of the hand held units, but I like that all the dust is kept within the unit and the speed and effectiveness is unquestioned. The unit is sturdy, heavy, the motor is strong....all is terrific....then how come only four stars....because they left out the hole for 1/8" electrodes. For those you need to spend hundreds more for the next model up....that's just absurd. So, I will eventually take the attachment off, bring it over to the mill and drill a precise 1/8" hole....and save a bunch of money....As to recommending it....I'm not sure....no doubt this was kind of a splurge based on my questionable? particular issue with tungsten dust. But if you are not using thoriated electrodes, you probably can buy a sharpener for far less.

Not very powerful

The Piranha will grind tungsten but the motor is small and not very powerful...easily stalled. The grinder also expels a lot of grinding dust which can be hazardous. Expensive for what you get.

Fast, Near Perfect Tip Profiles
March 11, 2017
I have a small prototype shop where occasional TIG work is required. This diamond grinder generates a range of tip angles very quickly with amazing consistency. The mess associated with silicon carbide wheels is in the past now. Have not had long enough to determine wheel life, but should last a long time when sensible feed rate against the wheel is used.
Pros
  • Arrived quickly, no damage, quick set-up, great results
Cons
  • None

Great quality equipment

This is a well made, quiet sharpener. the point it creates is precise.
Pros
  • Diamond wheel is thick and does not deflect or wear as fast. Plenty of space to move to when you do wear a ring in it.
Cons
  • The unit should come standard with the shorter collet holder for allowing the welder to sharpen shorter tungstens.
