How do you remove burrs from holes drilled in steel and aluminum? I tried using a larger size drill bit and twisting it by hand but it seemed to countersink a little...
I use a larger drill sometimes, or a countersink tool. It's generally OK to have a slight countersink. More often I use a special deburring tool with a little swlveling hooked cutter that works very well; the nice thing about them is that you can deburr the back side of a blind hole with them.
I use this for small drilled holes. Works great. I usually spin it by hand, as my drill puts enough pressue on the bit to remove more material than I want. One turn is all it takes.

I generally use the same tool as Ryan except I chuck it into an electric screw driver--makes quick work of deburring especially when you have a lot of holes like in a fuse or wing skin.
Depends on how many holes and what materials. BearTex wheels, ScotchBrite disks, large bits, broken off file sections with a grip glued to them, and for hundreds of holes at a time in thicker materials there is this:

I used a variety of tools w/this speed deburrer being the most used:http://www.aircraft-tool.com/shop/de...DUCT_ID=SP275A
The tool Dana highlighted is great for holes you can't see the other side of and for doing the edge of aluminum sheet.
This tool is a homemade version, it is a bic pen holder with a dremel bit glued in, it is great for doing the inside of a C channel or other places the speed deburrer can't go: http://webhosting.web.com/imagelib/s...g&target=_self
Will the swiveling blade tool work on small holes?...like 3/16 inch in diameter?
Yes it will but the speed deburrer is best for a hole you can get to both sides on. The swiveling tool is designed to do the edge of a sheet but can be used for holes. The speed deburrer is named appropriately...I had approx 10,000 holes in my plane and "speed" was very helpful.
I use this one. Costs more than the one in the Spruce link above, but it comes with an extension for doing across ribs or channels, etc.

Phillips screwdriver.
One or two holes held in my hand.
Lots of holes; spun between my palms.
I own a real manual offset speed deburrer but it stays in the box most times...
