- 3mirrors Tungsten Electrode Sharpener Grinder For TIG welding, Four-angle Tungsten Electrode,TIG Welding Rotary Tool With Flat Grinding Block, Multi-Angle Offsets,5 Diamond Wheels, 2 CNC Mandrels

This is an excellent product and works perfectly. Produces a very fine point. And the biggest plus, it doesn't create the big mess that a grinder does. As a beginning TIG welder this is probably my most useful accessory.

I liked the simplicity of this tungsten sharpener and the number of diamond disk included, but it is a bit pricey for the type of components in the tool. However, in comparison to other competing products the price is acceptable if it holds up over the long run. So far, I have used it for a few weeks and it seems ok. I did buy some additional diamond disk from another Amazon source, as I anticipate the disk will wear fairly quickly given the hardness of the tungsten and the very thin nature of the disks. A few additional observations, the brass inserts are very tight which keeps the angle very precise, but if the tungsten picks up any oxidation and needs resharpening, the electrode can be difficult to insert also you are limited to only one degree of angle for each size of tungsten. I must admit my reservation regarding price is moderated by the highly convenient access to resharpening provided by this tool. I keep it adjacent to my welding bench and can resharpen without getting up.

Grinder motor is a good solid unit the electrode grinding attachment is well designed and appears to be durable The supplied grinder arbors (2) arrived bent with substantial runout resulting in electrodes with unacceptable finish Overall unit is a quality item just be aware that arbors may require replacement

This is a fantastic tool and a great time saver. Set up instructions could have been a little more clear with the "bone shaped" piece. Otherwise, it's great. Easy to get different angles but switching out the screws.

This is junk! Don’t waste your money! The disk wears out a spot in seconds. Haven’t completed a sharpening not one. It would take 24 disks to sharpen one tungsten! I wished i haded bought it!

Seems like they work pretty well, buy extra disc I can see going through a few..

As a current student of welding and sharing a tungsten table grinder with 15 classmates, this was the best choice made. Able to grind whenever I need to and don’t need to wait in line. It’s lightweight, can adjust different angles and speed settings, sharpens and cleans tungsten just as good as our class table grinder.

So I have been using a 12” sanding wheel to sharpen my tungsten tips for the last few years and finally decided to get one of these Dremel type sharpeners so I could have more consistent angle on my tips. Here is what I have decided after sharpening about 200 tips. PRO: you get exactly the same angle every time. It’s pretty fast. The included grinding wheels will probably sharpen at least 200 tips per side before needing replaced (I’m still using the first side of the first wheel at about that count and don’t plan to flip it any time soon). Having the same angle every time makes my welds more consistent. The smoothness of the grind is better and so it makes the arc better in my opinion. My tips seem to be lasting a lot longer as a result of the better grind finish so I spend less time sharpening and more time welding. CONS: Damn these things are expensive for what they are but they are ALL around the same price so there doesn’t seem to be any deals to be had out there. You can only sharpen a piece that is about 1.5” or longer. This can be a problem if, like me, you are using a very short torch head and welding in tight access areas a lot. I use my tips until they get pretty short because I weld race car chassis and have to get in really tight places.

Works well, directions are pathetic and you can not tighten collet with wrench which was NOT included! So you can not put wheel assembly together then put head on machine you have to put head on machine then put wheel together and install OR there is a little slit that you could put mandrell in collet tighten it THEN put head on machine and try putting disk on mandrel? either way not the easiest to do in my opinion

Cannot get tungsten sharpened to the angle I prefer. Its one extreme to the other. Also you only use a single track of the disks. Wasting 85% of them.
