3mirrors Angle Grinder Aluminum Tungsten Electrode Sharpener Grinding Angle Controller& 5inch Diamond Grinding Wheel TIG Welding Tools with Gasket

I have not yet put it together and used it, I have to weld the bolt on first. To position the bolt I put it in my lathe and drilled and tapped 6-32 then carefully placed a hole in the guard. Then attached it with a screw. This is going to make holding the bolt in place for welding much easier. It would be very good for the maker to do this easy improvement. Other than that it looks like it will do the job well.

Just as required and easy to use.

The diamond wheels are perfect the design of the mechanics are perfect. My tungsten holder was drilled excessive leading to the winged bolt not being able to tighten it just falls out.

I don't do a lot of TIG welding, but I was tired of wearing down my normal grinding wheel each time I had to clean up the electrode. The directions call for you to weld a threaded bolt onto your grinder guard so that you can mount the angle guide. I use my grinder for all manner of projects and I don't need a bolt sticking out from it and getting in the way, so I completely disregarded the guide and I just clamp the grinder in a vice and then free-handing the angle on the electrode. This does a great job for my kind of use, but if I was doing a whole lot of sharpening, I'd either get a dedicated grinder to use with this kit or just get a free-standing grinder. For the occasional use I give it, this works just fine.

The electrode holder is nicely finished and easy to set in position. The concave back of the mounting screw is a nice detail, and there are two of them included in the package. The grinding disks themselves are very densely coated in grit, and over a broad area. The instuctions are poorly-written and don't include any information on the alloy of the mounting screws, which would be a good addition considering they're expected to be welded to the steel grinder guard.

It's to small. I get one angle. Arms need to be longer.

The concept for this product is pretty ingenious, and after you get everything set up, it’s very easy to use. But the directions are in broken English, and some of the word choices are downright confusing. I mostly went off the pictures, and attempted to figure out what they were trying to say.Some tungsten sharpeners out there are ridiculously expensive! This falls in the category of the under $100 range, and for that I applaud their attempt to get the price down. That being said, you have to provide the angle grinder to make this thing work, and you weld a stud onto your guard, their fixture attaches to this. My issue with the whole thing is when you’re welding the stud to the guard you better make sure you are true, otherwise all your measurements will be messed up. On the bottom side of the stud they’ve cut a concave to help you accurately put it on the guard, and somehow I was able to weld it right on the money. for the welders out there who immediately throw away your guard, you’re SOL…This kit included absolutely everything you need to get up and running, including nuts to help you hold the diamond grinding plate in place if your grinder doesn’t have the appropriate kind (looking at you Bosch). They also include two mounting nuts, and every size sleeve for tungsten you can imagine. I only use 3/32, but they literally include every size out there. Two different grit diamond grinding discs came in the box, and they are not the stupid cheap kind.If you are fine with everything I’ve described in the process to get this thing working then you’ll probably love this as much as I do. I had at least two old grinders I could think of to weld the stud on, and dedicate solely for sharpening tungsten. I suppose you could weld the stud on the guard of an active grinder, and then just take the guard off, but I don’t recommend it. Not only a pain in the butt, it’s dangerous.All things considered I do recommend this tungsten sharpener. For the price point, and ease-of-use once you get it working I love it. If anything changes in the future I’ll come back and edit this post.

Thank you!

I fitted one to a cordless 75mm cutter grinder using a 75mm (3") ceramic diamond disc. Disc not supplied.
