Jan,
    What if you used a carbide ball mill? Tilting the 
board or bit would expose the board to the bussiness 
end of the bit. The side of the ball cuts better than 
the tip. Ask your dentist about the technique. When 
you draw on glass, you tilt the bit! A round diamond 
bit is used. Very fine clean work can be obtained.
