Milwaukee tungsten grinder

[Bellaireroad]

There is a cordless tungsten grinder “ sharpie DX”, that is sold by arc zone

I don’t see this on the Milwaukee website. Is this something made by arc zone with Milwaukee parts?

Kind of looks like a rotary tool with a special head.

I have one and it is a Milwaukee rotary tool with a special head on it so you won’t see it on their website. I like it a lot, the head has interchangeable pilots for different tungsten sizes as well as a slot in the back to cut them down to fit small torch setups and a series of holes in the top to blunt the tip after sharpening.

Here are the poor mans versions you put on your own Milwaukee rotary tool.

I actually have one of the ARC-ZONE grinders that is mounted on a plain old orange Black & Decker tool that it came with 5 or 6 years ago.

Now I need to see if it will work on my Milwaukee M12....... Lets hope

Never thought to try it.

I'd like The Milwaukee rotary tool being 120V.
In 5 years or sooner the battery would be an issue....more batteries to buy at too much $$$.

Interesting.... much less expensive to “roll your own”

Please post results if you get it to work, thanks

Tried it tonight on my M12 grinder. Unfortunately, it did not work with the original ARC ZONE parts.

The shaft on the Milwaukee is about 1/4 longer than the B&D, also the collet didn't go down as far into the shaft. The collet nut then hits the inside of the grinder attachment because it sits off the grinder farther.

I think with a little modification or even trying a different collet and collet nut it might work.

Any others have this one from Arc Zone? Would you buy again?

I have the corded version from Techsouth. It is indispensable out in the field. I have considered the cordless version but I can’t justify the price just for convenience.

I don’t use it in the shop. I only use it when I can’t use my bench grinder.

Thanks, dr_clyde. I just started learning Tig welding and put a new 80 grit belt on my belt grinder and have been using that but was looking at these as alternative. Will be curious if they have sales for BF/CM.

I have one of these on a Black & Decker:

Then I bought one of these to take its place:

I also have the corded version . I did take it apart and it would seem to fit a milwaukee with little modification. I just leave it on the corded version because usually when tig welding there is shore power and I like having it stay dedicated to what it's intended use is. I also have a cordless rotary tool out when I'm tig welding to clean or as brush on it.

I just use a normal pedestal grinder with a dedicated Alu oxide wheel. And turn my grinders by hand. About 10-20 at a time depending on the job / time available etc. We had one of the corded table top sharpeners in college. It was mega expensive new and kept breaking as people used it day in and day out. So your chances of having a sharp tungsten in minutes were zero. 20 mins queue was the norm. And then it wouldn’t sharpen all of a sudden. I was forced to learn to sharpen on a grinder and belt sander. Glad I did as I never needed a gadget to sharpen tungsten for me ever. Waste of money for a decent welder.

Until you’re orbital welding and need consistency on your points, or in a tank, up on a lift or out in the field where there isn’t a bench grinder or belt sander.

Not everyone only welds in the shop. A battery powered portable tungsten grinder is brilliant for mobile work.

Several versions of that grinder head on Ebay, and for <$100.

Most dremel like tools have the same threaded head, 3/4" iirc. Screw one on and go.

$377 is hefty for what can be had for $150 or less.

 

[pcmeiners]

Have a Techsouth (corded) also, off Ebay. Same exact head as the OPs , which has fully adjustable grind angle, multiple electrode size collets (3) for less then half the price, without a scratch on... likely used twice if that. Why pay more than twice as much ?, makes no sense, unless you need it instantly.

 

[dr_clyde]

This is one of those tools that industry has had for years and now the hobby shop has discovered and thinks is way expensive.

Upside of an 80-100k orbital machine, $350 for a tungsten grinder is peanuts.

"Upside of an 80-100k orbital machine, $350 for a tungsten grinder is peanuts."

True but most look at it as an aluminum head which the Chinese could produce for $15 and a motor cost of $15-35. Granted , one bad weld could cost more then $350 . Sort of like Snap-on pricing
