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.

Works great

Just received this tungsten electrode sharpener and at first I was VERY impressed with the quality of the grinder head and with the number of sharpening wheels that came with it. However, after assembly, I went to sharpen some tungsten electrodes, and when I turned on my Dremel, I thought it was going to vibrate right out of my hand! The diamond wheels that came with the unit are severely lacking in quality (balance); they are not anywhere near the quality that you would expect, especially looking at the quality of the grinder head. Since the Dremel was limited in speed due to vibrations, it took me longer than it should have to sharpen my tungsten electrodes. The accuracy of the angles in grinder head are pretty good and after finishing the grinding, it appeared that the sharpened electrodes had a slight swirl marking (as opposed to a straight in-line grind) due to the way that the tungsten was hitting the grinding wheel (not too sure how this will affect the arc during welding). I guess, for the price, it is worth it. The actual grinder head is much larger than I expected and a little heavier too, but overall, I like it. If somehow they could manage to provide a quality (BALANCED) grinding wheel(s) I would have given it a 5 star rating.

This fits my dremel nicely and makes it easy to grind a perfect point on my tungstens. Just have a little patience and feed gently and twist the electrode, repeating until the point is as you like it. Maybe a bench grinder is faster, but you’d need a jig for that, or skill to hold the proper angle. No skill required with this jig. A couple of tips. Obviously, wear safety glasses. I’d advise against using the edge of the wheel to trim off contaminated tips. But if you must, safety glasses PLUS a face shield would be a real good idea. Yesterday, I discovered I can use the edge of the wheel to trim off my tungsten ends, wearing just safety glasses, I did this several times. Doesn’t work so great, I mostly just aimed to score the electrode so I could easily snap off the fouled end with pliers. Well, one tungsten decides to get caught, and snapped down the middle, then were flung with considerable force straight into my safety glasses. If I hadn’t been wearing them, I would have been seriously injured and probably blind in one or both eyes. I could have just as easily been hit on my mouth, nose, cheek… it would have been disfiguring. Full face shield and front protective gear would be the only way to protect against such foolishness. Best to just use the jig for grinding the tips only, as the tool is intended for, that way the tungsten can’t get caught. Tip #2. Remove the jig from your rotary tool over a trash can. The jig captures all the grinding dust during operation, and it collects in the bottom of the jig. Just like taking apart a pencil sharpener, when you take apart the jig, the tungsten dust wants to fall out. I really like how it collects the dust though. My final thought is I will probably buy a cordless rotary tool to dedicated to this jig. Less hassle than tying up my main dremel, and cordless will be a lot handier on my welding table. Just beware, not all cordless rotary tools have the standard dremel threaded accessory end.

The sharpener it self is amazing, as others have stated it didnt fit on my dremel due to arbor height but it fit great on my other grinders. The reason for the 3 star review is the disks, first off the shafts I got with the grinder are bent and wobble, secondly the grinding disks are garbage i get about 1 tungsten out of it. Finding the right size of disk has been tricky as well there dosent seam to be a ton of options in that size of disk.

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.
