SONNLER Tungsten Electrode Sharpener Grinder Head,TIG Welding Tool with Cut-Off Slot with 6 size 8Angles, 48 Holes, 10 Double Diamond Wheels, 3 CNC Mandrel Suitable For Most Rotary tool

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.

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.

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.

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.

I saw some reviews that really made me question this device, but I have to say that it really does work very well. However, here are a couple of things to note. - The holes in the wheels are a bit big, so that can cause them to be out of balance under high RPM. Taking care to be sure they’re centered can minimize vibration. - The quick chuck that comes with many tools will not allow the grinding wheel to sit low enough, but using the standard collet style chuck puts the wheel in the perfect location. - Also to stop the tungsten particles from being thrown out I was able to find a shop vac adapter that with minimal work, screwed right in to the tool. I’ve now sharpened several tips all with the same wheel and it shows no sign of wear at all.
