Inexpensive alternative for TIG electrode sharpening.
This is all you need if you are just learning to TIG. Fitted it on a Milwaukee M12 Rotary Tool and sharpened all my tungsten. Works great and gives you a lot of options. Nice and sturdy too, made from aluminum.

Maybe the best dremel based tool made
This is my new favorite welding gadget. It is very easy to install on a dremel tool and was a perfect fit. It is easy to remove if you need to repurpose. It works much like any screw on attachment you would use on a dremel and uses the standard collet size. As another customer mentioned it works best with a lighter effort and produces a very nice , sharp point. If you have a seldon used dremel laying around it will make for an inexpensive useful tool.

High quality and works well
This tungsten sharpener is great, and more premium than I had expected. The anodizing is perfect and the holes are as well. My only complaint is I wish the disc holder was shorter, it's all the way in my M12 rotary tool but is about 1/16” too far protruded, so my angles are slightly off. It really doesn't matter though, not enough to subtract a star.

The best value for a tungsten grinder
Works beautifully and excellent value, just one gripe i have is after one sharpen the face of the diamond disc noticeably wore out but maybe theres a better quality disc out there. Comes out super sharp and jig fit perfect on a milwaukee rotary nicely.

Best way to sharpen
Just got this and wish I would have sooner. Works as expected and it's solid. Not sure in some of the other reviews. They most likely didn't read the basic directions if they couldn't get it set up properly. It's easy and straightforward. Just measure as shown, then look through the alignment hole and the disk should be centered. Also saw a review about only one grind angle. No idea how you could even achieve that. Pictured are all the choices of angles when set correctly. Sure beats my old method of chucking in a drill and a bench grinder. Will update my review if anything changes, but I don't see how that would change.
