Tungsten Electrode Sharpener Grinder Head,TIG Welding Tool with Cut-Off Slot with 6 size 8Angles, 48 Holes, 5 Double Diamond Wheels, 3 CNC Mandrel

I don't understand what is going on here. You state this electrode sharpener can go on any rotary tool with 18mm diameter threaded neck, but I've tried to put it on both Dremel and Tacklife rotary tools, but it will not thread on either. I nearly ruined the threads on the Tacklife grinder. Given this information, I went back on Amazon to buy a Sonnler rotary grinder without the head, BUT YOU DON'T SELL IT BY ITSELF! What!? What am I supposed to do with this thing now? What is the thread size on this attachment? What manufacturers other THAN Sonnler use it? Why don't you sell the grinder that goes with it? This is incredibly ridiculous and frustrating. Get your stuff together. Extremely unsatisfied. 0 stars if I could.

Terrific product. work well.But, it does not fit onto most rotary tools, in the end I took it to several hardware stores and started fitting it to the various rotary tools they had in stock. Finally I found one, the Tork Craft which it fitted well. At home I had two Dremels and one Ryobi that did not fit. So do not believe the claim that it will fit most rotary tools.

As stated on another review, does NOT fit ANY rotary tool. Only decent use is as a paperweight. Returning asap and getting a Sharpie DXCL head instead
