@Madda,
it is hard to give you an exact value for the precision, only one example: for the ball bearings I had to mill a hole with a diameter of 16mm. I used a two flute milling cutter with a diameter of 3mm and the result was a hole with dia 16mm +0,01 / -0,01 mm and it was perfect to press the ball bearing in it.
