3mirrors Cordless Tungsten Electrode Grinder Sharpener TIG Welding Tool w/12V Lithium Battery Rotary Hand-Held 4 Holes w/Multi-Angle &Offsets, CNC Mandrels, Diamond Wheels, Portable

I recently purchased this cordless grinder, and I must say, the body is really nice. It comes with two batteries and a charger, which is great. However, the plastic angle jig that comes with it only has a single point for positioning and is minimally stable and prone to wear. One downside is that you need to supply your own wrench, but luckily I had one in my toolbox that worked with the 3/8" standard Dremel collet size.Once I put it together, it worked well. The markings for the angles are clear, which makes it easier to use. If you keep the clear cover on, it's even better. The attachment is nicely made overall and keeps the angle for you. The supplied wheels work fine too.As someone who has broken many tungsten rods during my 3 semesters of welding, this is a great little tool. I tested it on some small pieces and found that, like the wheel, care must be taken when grinding as the rod can snap easily. This tool takes the guesswork out of the angle needed to hold the rod. It can be a bit loud in higher speeds and can spark a bit, but the cover helps prevent injury and dust. The instructions on assembly could be better, and I'm still not sure what the black rings or button on the side are for, but I haven't needed them so far. The tool comes with extra sanding discs and mandrel. The top bar is not super tight, but it helps prevent fingers from being injured, so I hold it upright. I even attached a before and after picture of my testing. Like using a wheel, the rod can get hot.Using this tool has saved me a lot of time and money by not breaking rods anymore. It's great to know that it can be used for quite a few things, but I doubt I'll need to use it for anything other than welding. Level 6 can get a little loud, but I'm sensitive to loud noise. Ear plugs do help, though. Besides, using a wheel is louder. I almost forgot to mention that the battery charged in just 20 minutes.Overall, I'm really happy to be welding again, and this tool makes it so much easier. I would definitely recommend it.

This is a very nice grinder, very easy to use and I love the life of the battery. Great value for money.

You need to supply your own wrench. 3/8" standard Dremel collet size.Once put together, it works. I suppose the only downside is if you use multiple sizes and/or angles. But the markings for the angles are clear. If you don't keep the clear cover on, it's even easier.But the attachment is nicely made overall. It keeps the angle for you and the supplied wheels work fine.

This grinder is exactly what I was looking for. I am happy with how long the battery lasts, and the overall performance of this tool. I do wish that it had some kind of carrying case included but since it doesn’t, the box, at least has separators so that each of the parts is in its own place. It’s always so hard to keep accessories together with tools. I think the price is a little high, but then again, I’m very satisfied with how well it performs.

I broke many-a-tungsten rod during my 3 semesters of welding. This is a great little tool. Tested it on these small pieces and like the wheel, care must be taken where we hold while grinding. Rod can snap easily. This tool takes the guesswork out of angle to hold rod. It is loud in higher speeds and can spark a bit, but cover helps prevent injury and dust. Yay! Instructions on assembly could be better. Not sure what the black rings or button on side are for, but so far not needed. Comes with extra sanding discs and mandrel. Top bar not super tight but helps prevent our fingers from being injured, so hold upright. I attached a before and after my testing. Like using a wheel, rod can get hot.Time and money saved by not breaking rods makes this a wonderful tool. Great to know it can be used for quite a few things, but doubt I will.

Almost forgot, battery charged in 20 minutes.Meanwhile, happy to be welding again. This makes it easier.

This is powerful enough to get the job done. Unique color but I don’t hate it. Comes with few attachments. I have only used the grinder so far. I love it. I recommend it. Sharpening is a good idea too. Can’t wait to try that.
