A rumble strip milling machine (101) has a plurality of cutting wheels (309, 310, 311, 312) mounted on an associated axel (321). Each cutting wheel has one row of cutting teeth (317), which are oriented 90 degrees out of phase (e.g. 6, 9, 12, 3 o'clock). Each cutting tooth (317) has a cutting tip (323).
