ABSTRACT:
An expanding machine reamer whose cutter head has an imperforate core portion and three axially elongated rib portions radially projecting from the core portion in circumferentially spaced relationship. The rib portions are each formed with three bores approximately perpendicular to a common axial plane. A first bore receives a clamping screw engaging a clamping shoe which holds a cutting blade against a flank of the rib portion, second and third bores hold wedge-shaped abutment members radially engaging the blade and backing screws by means of which the radial position and the inclination of the cutting edge of the blade may be adjusted.
