For a rotor type block you will want 1/4" DRILL bit (3/16" might be better), and a 1/16" end mill to connect the grid. Don't try and use the endmill for plunge drilling unless it is a ball nosed one. Once you get the holes drilled you can then plung the endmill in the drilled holes to flatten the bottom of the holes. Not sure if that would help or not though.

If 1/4" is the smallest you got and you want to mill something then try a maze design or something.
