The milling cutter head has slots to receive bit holders; each holder is a plate-like body formed with an opening to hold the bit, and a pair of slits directed to the opening which define, therebetween, a tongue extending in the direction toward the opening into which the bit is inserted. By pressing the tongue toward or away from the slits, for example by means of a screw bearing against the side of the tongue, the position of the bit with respect to the cutting plane can be adjusted. The holder is additionally formed with a bearing surface fitting on the milling head, the bearing surface having a screw which can be screwed to extend slightly therefrom and thus tip the entire holder about the front edge of the milling cutter head, to provide for angular adjustment.
