ABSTRACT A Rosser type debarker head has a plurality of rounded, indexable cutting teeth spaced in patterns of repeated rows running axially the length of the cylindrical surface, each tooth being spaced along the cylindrical surface so that the total cutting pattern produced by a single rotation of the head creates a uniform round toothed scalloped effect. Each tooth is shadowed by adjacent offset teeth so that only the portion of the round tooth outside of a cord representing essentially one-sixth of the circumference of the tooth is exposed to direct cutting impact. The remainder of the round tooth is shadowed by adjacent cutter teeth. As a result, the debarker head produces a uniform scalloped cut, producing a shallow, smooth cut upon the log with limited splintering, while reducing the impact on the teeth so that tooth life is significantly extended.
