so I'm trying to make this robot head here

and I've created a cube for the head, set the xy subdivisions to about 20 per side, beveled the edges and added the ears. I want to make circular indents for the eyes with booleans by cutting with cylinders into the beveled cube, but it deletes both objects.

What's the best way to do this? is there a way to get a ring of verts into a perfect circle on the surface of a poly cube?
:headbang:

would it be easier to do the whole thing in NURBS?

EDIT: also,yes I did delete the construction history on the cube
