Any cons of lowering springs?

Yup, but don't get a 115. They will just fall apart on steel. The cutter you need will have to hack steel, but it will look almost identical to the one Kenchan posted.

This is what I used but you'll go through about 4 or more so I suggest something more serious. There is a bit of a learning curve involved when using them so you don't blow them up, but once you get the hang of it you can get about one hole elongated per bit before they're toast.

I'm thinking the back up cutter I bought but didn't use was one of these ones.

It needs to be able to hack steel. You can read what they'll cut in the description of each bit. Bits for soft metals won't survive, nor cut worth a s***. Using them will just piss you off, and you'll be under there all day cursing. Ask me how I know.
Oh, and Amazon usually has the Dremel bits real cheap if you can wait a few days to get them. I got the pair of 115s (or 117s) for a fraction of what they'd have cost me at my local Home Depot.

Something like this one cost me $19 CDN at Home Depot.
Look at what Amazon wants. If I was doing it all over again I'd get a pair of something like these. It'd be like a hot knife through butter. 104
