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.

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 great! I have this on a Wen rotary tool. I tried different angle settings and the angles are clearly different from each other (no clue what one reviewer was saying about how they're all the same). This is replacing another grinder I bought off Amazon, which also worked perfectly fine TBH, but had less angle options.

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.

The biggest issue with the sharpener is setting up the correct location/stickout of the mandrel so the diamond wheel lines up with the alignment hole/measurement. Once you get that set and locked separate the upper piece with the tungsten angle holes in it from the base then screw on the base onto your Dremel style tool. I used a generic on I bought separately dedicated for this purpose so I don't have to continually setup the tool to use it as I sharpen a LOT of tungstens when welding.I find that the tool gives me a quick way to put a point on the tungsten. The angles appear to be pretty correct, I haven't verified that every angle is perfect and if you notice after a bit of time some wobble will develop in the holes you feed the tungstens through if you use a drill to spin the tungstens as I do otherwise probably won't wear much. But the real world an exact angel to me isn't a requirement, more the general angle/shape of a sharp point with clean sides parallel grind marks on the tungsten leading to a more stable arc. I have yet to wear out the include diamond sharpening disks but I don't push excessively hard on the tungsten when putting a new point on tungstens, as with any grinder, file, sander... let the tool do the work, don't force it. If you force it that will just wear things out faster and your results probably won't justify the cost of replacing parts all the time.I feel it is a well made product and gives me good quality angles in the desired degree ranges I use often and it literally only takes few seconds, maybe 30 at most to get a good sharp tungsten every time, even from a flat start. I don't use the "triming" slot because I find it hard to control the tungsten stuffed down in the hole without any other support, it just ends up jamming the tungsten against the diamond when and the inside of the jig.I highly recommend it and expect to have it for a long time. Allows me to quickly prep my gear and keep welding.

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.

Paired with a Milwaukee dremel and works great

Works well but doesn't fit Dremel. It will screw on but the Dremel chuck sits too high. Had to buy a new rotary tool but fits new one perfectly. The grinding wheels are cheap but at least they are two sided and it comes with plenty of them.
