Expensive for what it is, but also worth it in the long run 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. Its pretty fast. The included grinding wheels will probably sharpen at least 200 tips per side before needing replaced (Im still using the first side of the first wheel at about that count and dont 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 doesnt 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.
