You can route out an area of wood with a regular "straight bit".  If you are talking about the kind of bit where a bearing rides along the edge so you cut in a certain distance, that is called a "rabbeting bit".

I used a straight bit to recess my trackball.  Layout the trackball template down and cut out the center section first and then drill the 4 holes.  Basically I just lowered the bit the same thickness as the trackball plate and then tested it out on a piece of scrap MDF.  Once I knew the distance from the edge of the router to the cut, I made some small marks on my CP and clamped a straight edge down and made the cut.  Once the outside edges were done it was easy to freehand out the middle.
