3mirrors ALUMINUM Tungsten Electrode Sharpener Grinder TIG Welding Tool Single Column Open Design w/Cut-Off Slot Multi-Angle &Offsets, Horizontal Hole, 4 Screw Holes &2X CNC Mandrel &5X 25mm Wheels

Awesome product. Works perfectly.

Bought this because I was sick of hand grinding my tips. Gives good accurate tips consistently. I put on my milwaukee M12 rotary tool. Set it on 2.5 out of 6 speed, does awesome job. I just leave it on there as a dedicated tungsten grinder. I bought this one verses the one with 40 holes in it, so can just have (1) 3/32 Hole- no confusion. If anyone has a hesitation on buying a tungsten grinder- like I was? Don’t be- you will be glad the first time you use it!Update:You can move the 3/32” brass guide to any of the 4 bevels you want. The way it’s marked is deceiving.

Not a bad little sharpener. The body is well machined and solid aluminum.. the instructions it comes with are horrible. Talks about installing o-rings and dust shield. Non of which come with or are part of this unit. Might have been for an older or newer design 🤔But functions well. I sharpened 20 - 3/32 with no issue and quite fast. The diamond blades are on the cheaper side but do the trick. Nice part is if you do it over a bucket there is no shavings all over.

Being a hobby TIG welder I would use a benchtop grinder and a drill to sharpen the tungsten welding tips. It was messy and just did an okay job. I would have loved a professional sharpener but they are hundreds of dollars. I came across this and realized I had a Dremel lying around not getting much use so I decided to give it a shot. I'm so glad I did. I paid about $60 for it and it works like a charm. It's very convenient and a bargain compared to other options. The quality is very good. I used it today and had some of the cleanest welds I have had in a long time.

I originally was going to return this because I couldn't get it to work. The instructions are laughable; they would have been just as useful had they been written in Mandarin. I eventually figured out how to mount it onto my Dremel tool and adjust the grinding disc, and it works. The description makes you think you're buying a grinder; this is merely the attachment for a rotary tool. I can't speak yet to longevity.

Using on a cordless Dremel tool, makes sharpening tungsten fast and easy. Ruined first disc by using too much pressure. Now have the hang of it and it makes the job faster, keep it at the table and if I stick the electrode, I chkange it, let it cook then resharpen it.

I've had good luck with this. You do have to gentle inserting the tungsten so you don't apply too much pressure to diamond disk but other than that it makes a perfect grind!

Will pay you back in time you save walking to the grinder
