Rotary cutters for ringer debarkers each have multiple cutter units secured together in coaxial staggered relation. Each cutter unit has gullets between gauge lands, and has knives in the gullets clamped against the leading side of the lands by wedging keys secured in the gullets. The staggering of the cutter units provides each knife with a gauge land on one of the other units for cutting depth control.
