Concrete Scarifier - Concrete Surface Preparation. Scarifiers, also called concrete planers or milling machines, remove concrete faster and more aggressively than grinders . That's because they use the pummeling action of multi-tipped cutting wheels, or flails, that rotate at high speeds to chip away at the concrete surface.
