milwaukee m18 drills, off center spinning?

[hypebeastwelder]

Hey, so i TIG weld and i use a drill to sharpen my tungstens on a bench grinder with a 320grit diamond/glass grinding wheel (most efficient way to sharpen tungsten in my opinion). 

 

Now my issue is that i just bought a whole set of milwaukee FUEL power tools and the drill is brand spanking new.

 

But when i use it to sharpen my tungsten, it turns eccentrically causing my tungsten to sharpen unevenly. 

 

I used my 'shitty' old DEwalt drill and boom its turning straight. 

 

I've tried this with a few other milwaukee drills and they all have the same problem. 

 

Why is that?

Milwaukee’s chuck wobble (runout) is pretty well documented.
Of all the brands, they are probably the worst offender.

There are YouTube videos of guys fixing the chucks by grinding/boring on a lathe etc.
I wound up exchanging mine and going through a couple at HD until I got one that appeared to be ok. ( it was still off a bit).

Can you exchange it?

Question is, why would you change brands if you never had problems with the dewalts?

Both me and a good friend of mine have only Milwaukee and have always used our drills to sharpen tungsten and never had a problem.

I own no less than 5 Milwaukee drills and none exhibit any wobble, sounds like you got a bad one. Call Milwaukee and work an exchange or repair, they're good for it.
