Tungsten Electrode Sharpener Grinder For TIG welding, 6 Sizes 10 Angles, TIG Welding Rotary Tool With Flat Grinding Block Cut-Off Slot, 10 Diamond Wheels, 3 CNC Mandrels

This tool is extremely useful and sharpens welding rod at the angle of your choice super quickly and easily. The rotary tool is a very well made unit that has a widely variable speed. It can go up to 30,000 rpm but I’ve only used it at much lower speeds for optimal results and to preserve the diamond cutting disks. The kit comes with 10 of these large diamond disks which seem to last for a long time. The most impressive part of the kit is the heavy aluminum guide that screws to the front of the tool over the cutting disk. It has many sets of holes for the different angles and diameter of rod you are shaping. This guard it very thick and beautifully anodized which helps guide the rod precisely to the desired angle.The guard was much nicer than expected and, like any top quality tool, should last a lifetime. As testament to the intended longevity of this tool, extra brushes are included with the rotary tool.In addition to perfectly sharpening welding rod, I’ve found that it this tool can be used to precisely sharpen tiny flat head screwdrivers used for watch making, and other industries requiring fine assembly.I gave this kit 5 out of 5 stars as it far exceeded my expectations but it is not perfect. It can sharpen rods and screwdrivers at eight present angles which is plenty but I realized that by adding more sets of holes it could be made to grind at more angles if the manufacturer wanted to change it slightly. It also takes a little trial and error to get the diamond cutting wheel at just the perfect height. This only takes a minute or so and gets easier with experience. Finally, it would be great if the tool could be stored in the nice black clamshell storage case while the cutting wheel and angle guard were attached to the rotary tool. As it is now, it must be disassembled each time you want to put it into the case. These are very minor issues and don’t even add up to even half a star off the rating. Nothing is perfect but his tool is as close as I’ve found.

This is a great tool for a hobbyist welder, not sure how it would hold up in a production environment but it’s sharpened a lot of tungsten since I’ve had it. It makes it easy to get accurate grind angles and clean points on your TIG tungsten in very little time. The diamond grinding wheels have been holding up very well, I believe I’m still on the first one and it comes with several replacements. Overall a nice tool for the money.

Great tool for the price! Works well, easy to set up, I use this tool in my personal shop but have the same one at my manufacturing job and use it everyday without issue.

Worked good for sharpening four tungsten and then the motor locked up. Recommend paying more for a good one. To only have been used four times and the motor goes out, don’t buy!!!!

Works well, but vibrates like hell on highest speed. Make sure you read the directions and have the arbor set at the proper height for this to work properly. It does a good job just turn down the speed and let it do its thing!

Overall, the aluminum 'head' barrel seems nicely fabricated, but unfortunately, the angles on it ARE ALL WRONG! The 'grinding discs' are super cheap, poorly made and feeble as the elder cut-off discs on the first Dremel models. Additionally, the speed rating on this is outrageously over powered. The vibration of this handheld 'dremel' is above what is necessary and at 'Level 1' (speed) is more than sufficient. Why there are other speeds, is ridiculous.Nice case and all, will be used very carefully and kept in the case otherwise but not sure about the long term usability. Hopefully it lasts and the bearings don't fail as others have stated.

This works great, easy to put together and use. Takes seconds to sharpen the tungsten rods to an extremely sharp point. I also like the adjustable speed dial.

Works great. Assembly took a little doing but the instructions were good. Diamond wheels make quick work of tungstens and get them super sharp. Well worth the cost.
