I went through my extensive collection of dremel bits, and I couldn't find anything that worked well to alter the whole position. 
Tried the diamond coated bits from Harbor Freight, even though the abrasive material usually just flakes off the bit.  Same thing happened.
Searched the stores until I could find the proper size file. 


My suggestion:
Harbor Freight chainsaw files!!

$4.99 for a pack of 3, different sizes.  They work faster than a crackhead stealing your Christmas decorations.  3 mm on both holes, in about 15-20 minutes. 
Return them, get your $5 back. 

returning a $5 tool, that did the job ?

even used tools need good homes

when you really want to take off the metal, use a 1/8" carbide burr in your dremel. real carbide, not Ti coated re-bar from HF

i have burrs that are like 8-9 years old, still cut fine, and don't complain much

Yeah, Harbor Freight is cool, but I wouldn't expect any of their stuff to perform nearly as well as pretty much any other brand. I got some of their dremel style cutting discs once and I went through a whole pack of discs cutting a two and a half inch hole in a pretty thin cast aluminum part. I was not impressed and changing discs every 30 seconds got old fast.

I've got three like this carbide burrs, but of different shapes:

But, I had no success with them. 
Makes no sense, I know, but they just don't work for me.  Unless you're talking about the silicon carbide "textured" bits, that look like diamond grinders.

Either way, I was hoping that someone could add an amend mum to the write-up.  Could save someone time and frustration. 



I found an awesome little dried up spider inside the cover, like in the write-up.  I love those little guys.  They're good luck.  Poor little guys, valiantly living out their lives in fruition,  sight unseen. 

I once made a trip to HF, and bought a tap and die set
but when I got home, my wallet felt light
because I couldn't tap shaZam! with the die

Seriously that store has THE shittiest tools I have ever seen.

You guys got anything else to add?  Maybe we can compare Lowe's to Home Depot? 

Lowes, hands down.
