Making bolt hole larger?
I'm making brackets to attach my factory seat brackets to a set Lancer Evo Recaro seats. I'm using a 3" wide, 1/8" thick steel strip. My measurements were slightly off, and the bolt holes I drilled are just a little misaligned. I want to elongate the holes a little bit, but it's a huge PITA. I used the sanding bands on my Dremel to do a couple of the bolt holes, but I used up every one I had. I also tried using a tapered grinding bit they had, but it didn't do much. Also, getting the bolt holes elongated enough by sanding took a lot of time. Anyone know a faster, easier way to do this?

A UNIBIT from HD or Lowes is what we use. Makes a round hole in thin material, and will enlarge the holes in steps..

You can get a "good enough" 1/4" electric die grinder
off eBay for about $15. Carbide tulip burr, under $5
(you may find them at Ace too). Ain't nothing gonna
stop that from hogging. Other than another chunk of
carbide, or you gum it up with aluminum.
