Using a 1/4 electric die grinder with double cut carbide bits is the best way to remove the bulk of the material. Going back over the area with a single cut bit will help make the surface a little smoother. It might also be wise to pick up a template from someone.

I usually use a "christmas tree" shaped bit. i.e.:

A little WD40 helps, I've noticed the burr is less likly to grab and jump. (not cool when you are working with critical sealing surfaces)
