Abstract: A shank has a support disk concentrically secured thereto. The support disk includes three radially extending slots and a pair of integral ribs adjacent each slot, each pair of ribs being disposed one on each side of the associated slot in longitudinal relationship therewith. A one-piece cutting member is mounted in each slot and includes support arms in sliding engagement with the ribs. An adjustment disk is concentrically mounted on the shank for rotation relative thereto; this disk includes arcuate slots each of which receives a projection on one of the cutting members. Movement of the adjustment disk provides for the simultaneous and equal radial movement of the cutting members. Clamping means are provided for releasably holding the cutting members in their selected positions.
