3mirrors ALUMINUM Tungsten Electrode Sharpener Grinder Head - Efficient TIG Welding Tool with Cut-Off Slot, Multi-Angle & Offsets, 4 Copper Screw Holes, 1X CNC Mandrel & 5X 25mm Diamond Wheels Review

Another professional welder that does side jobs outside of my home workshop looks like good value for money but it isn't. The main problem is that he uses the very edge of the wheel to sharpen the tungsten. When not forced to stay on the wheel, it sharpens tungsten with an off-center tip. Unfortunately, if you get a good tip, if it's that far from the edge of the wheel, you'll end up with a twisted grind. Sample. The same as in the description you want to avoid.

Bought because I was tired of sharpening tips by hand. Always gives good and accurate tips. I installed my Milwaukee M12 rotary tool. Set it to 2.5 out of 6 speeds, it does the job just fine. I just leave it there like a special tungsten grinder. I bought this verse with 40 holes so there can only be (1) 3/32 hole - no confusion. Anyone have doubts about buying a tungsten grinder like me? Don't - you will be happy the first time you use it! Update: You can move the 3/32" brass guide to any of…

This comes with brass knurling adjusted in certain degrees for different sizes of tungsten alloy. On my first use I used 3/32 in its original position, 20° I think it was too shallow a bevel for my preference. So I looked it up and found that knurls have a hex head and are interchangeable. I changed the 3/32 knurl to a .004 knurl and got the bevel I like on my tungsten. Also, you need to apply light pressure to the tungsten (almost barely touching and twisting) or you'll get a rough grind on…

It's really good with the smaller tungsten, although a little underpowered for a 3/32. much faster at 3/32 with a diamond wheel and drill bit. There are a couple of flaws that caught my eye straight away, there is some play in the holes which causes the tungsten to skew slightly when you turn it by hand and the diamond wheel bends a little making it difficult to sharpen evenly across the entire blade Scope but I just sharpened 3 x 10 packs of tungsten in about 15 minutes and am happy with the…

The brass inserts are just the right size for new electrodes and sharpen quickly. The instructions don't recommend a speed, but the lowest speed on my old Dremel worked fine. The device itself makes a very robust impression and should last a long time. Sharpening used electrodes is a bit more complicated. Even if the tip is not flattened, they seem to expand so much from the heat that they can no longer be inserted into the insert of the desired size. You should increase the size by a size or…

This product is perfect for my needs as I have my own tungsten sharpener. Welders can get a little nervous sharing a grinding wheel so this product gives me more confidence and saves me time by avoiding unnecessary trips to the grinding wheel. The aluminum body is thick enough to withstand a fall. The corner rails are interchangeable so corners can be easily adjusted. As long as you read the instructions that came with the product and DO NOT MIX the TUNGSTEN ON THE DISC, they will last quite a…
