A blade holder component secured to a revolving milling cutter body includes walls which define a recess for receiving a cutting blade, and which support the cutting blade inserted in the recess. The blade holder component incorporates an adjusting device having a resiliently deformable tongue which is defined by a single slot extending into the blade holder component from the zone of the blade-receiving recess. The tongue has a terminal portion including a support area for engaging the cutting blade received in the recess. A set screw passing through the tongue and traversing the slot is threadedly engaged in the blade holder component adjacent the tongue. By turning the set screw, the position of the resilient tongue is changed for altering the orientation of the cutting blade in the recess of the blade holder component.
