Any where. I used to be a millwright and we used steel and carbide blades and bits all the time to cut and remanufacture aluminum.
Carbide routers bit work wonders. Even the wood working ones with bearings on the end.
I will say if you use a carbide bit you might want to put a light coating of oil of some sort on so the chips don't plug up the teeth.
My luck varies FIXIT

For my instrument panel, I found that the Dremel worked well with the #115 High Speed Cutter or the #9901 tungsten carbide rotary file/carving bit. The sanding stone bits did not work well. For large aluminum shaping, I used a Vixen file.

A drywall cutting bit in a Dremel tool works pretty well.

Use a good quality carbide bit and use BOE Lube, usually the paste form. Are you using a pattern of wood?

I use amanatool for my CNC router bits. The 1/4" shank with a 1/8 tip works well and will probably fit in a hand router.

very helpful. Plan to use a wood pattern to follow the contours with the trim bit.
