Technician A is correct because rotors that are smaller than the machine-to or below the discard limit are too thin to safely use and must be replaced for safety reasons. Technician B is correct because rotors that are above the machine-to limit may still be serviceable if they meet certain conditions regarding parallelism, runout, and surface condition, indicating they can be safely reused.
