A cross feed cutting head for a rotating spindle includes a cutter assembly, driven to reciprocate as the head is rotated, and a balancing mechanism to compensate for the shifting mass of the cutter assembly. The balancing mechanism includes a plurality of annular races distributed along the radial periphery of the head. A plurality of counterweights are freely moveable in the races, and change position in the races to minimize static and dynamic imbalance caused by the reciprocation of the cutter assembly.
