Tungsten Electrode Sharpener Grinder Head,TIG Welding Tool with Cut-Off Slot with 6 size 8Angles, 48 Holes, 10 Double Diamond Wheels, 3 CNC Mandrel Suitable For Most Rotary tool

The biggest issue with the sharpener is setting up the correct location/stickout of the mandrel so the diamond wheel lines up with the alignment hole/measurement. Once you get that set and locked separate the upper piece with the tungsten angle holes in it from the base then screw on the base onto your Dremel style tool. I used a generic on I bought separately dedicated for this purpose so I don't have to continually setup the tool to use it as I sharpen a LOT of tungstens when welding.I find that the tool gives me a quick way to put a point on the tungsten. The angles appear to be pretty correct, I haven't verified that every angle is perfect and if you notice after a bit of time some wobble will develop in the holes you feed the tungstens through if you use a drill to spin the tungstens as I do otherwise probably won't wear much. But the real world an exact angel to me isn't a requirement, more the general angle/shape of a sharp point with clean sides parallel grind marks on the tungsten leading to a more stable arc. I have yet to wear out the include diamond sharpening disks but I don't push excessively hard on the tungsten when putting a new point on tungstens, as with any grinder, file, sander... let the tool do the work, don't force it. If you force it that will just wear things out faster and your results probably won't justify the cost of replacing parts all the time.I feel it is a well made product and gives me good quality angles in the desired degree ranges I use often and it literally only takes few seconds, maybe 30 at most to get a good sharp tungsten every time, even from a flat start. I don't use the "triming" slot because I find it hard to control the tungsten stuffed down in the hole without any other support, it just ends up jamming the tungsten against the diamond when and the inside of the jig.I highly recommend it and expect to have it for a long time. Allows me to quickly prep my gear and keep welding.

Great product for quick sharpening of tungsten. Fits great on a Milwaukee M12 brushless rotary. Diamond wheels do not last but replacements are cheap enough. I would recommend this one over any other design out there

I love it; it makes it easy to sharpen my tungsten

This is my new favorite welding gadget. It is very easy to install on a dremel tool and was a perfect fit. It is easy to remove if you need to repurpose. It works much like any screw on attachment you would use on a dremel and uses the standard collet size. As another customer mentioned it works best with a lighter effort and produces a very nice , sharp point. If you have a seldon used dremel laying around it will make for an inexpensive useful tool.

The sharpener it self is amazing, as others have stated it didnt fit on my dremel due to arbor height but it fit great on my other grinders. The reason for the 3 star review is the disks, first off the shafts I got with the grinder are bent and wobble, secondly the grinding disks are garbage i get about 1 tungsten out of it. Finding the right size of disk has been tricky as well there dosent seam to be a ton of options in that size of disk.
