Die grinder FTW
I just bought a die grinder last week and am already really loving this thing. It is like a Dremel, but on a horse sized dose of steroids.
Northern Industrial Air Die Grinder — 1/4in. Inlet, 3 CFM, 22,000 RPM, 90 PSI | Air Grinders | Northern Tool + Equipment
I figured out pretty quickly though it is a good idea to use it with a regulator: One, because it will empty the compressor tank FAST at full throttle. Two, because it is a powerful little bastard at 90+ psi

They make short work of exhaust tubing (both cutting and grinding welds), and it did a great job when I was cutting my firewall up for the swap.

You need a carbide rotary file/bur. I have two from Enco that will grind out just about anything- just keep 'em lubricated.
But when it comes to opening up holes, nothing beats a step drill. I picked up a three bit set Irwin set (like this one) from Enco and they have never failed me. Ranks high on the useful tool list for me. Cuts perfectly round holes when enlarging existing and in thinner metal too.
When it comes to the metal on metal cutting stuff I've had way better luck with Enco's inexpensive line than anybody else. HarborFreight's metal cutting bits and drills are useless if they're the cheap stuff.

^ That Enco stuff looks nice. The most recent thing I tried was this from HF, with limited success :lol:

Those carbide rotary bits are the only way o go for metal removal. Everything else is just for smoothing. Even on my underpowered Dremel, and in my slow speed drill, those types of bits cut through everything like butter. My hardened steel roll bar didn't resist at all. So I can only imagine on a good grinder. The tear drop shape is a good all round tool, so many angles on it, you can do some good shaping with it.

I bought a $300 Sioux Tools die grinder when I was building my airplane. It worked well for a couple of years. When it died I replaced it with an AmPro from Advance Auto for like $29. Couldn't see sinking another $300 in a die grinder. It was more powerful and has so far held up longer than the Sioux. I am really impressed with it for the $$$.
Buy it. Like it.
Oh, and those little 4" cutoff wheels from HF. I buy them by the 50 pack. Dirt cheap and use them for everything from cutting off to grinding. Awesome to have around.
