Floor grinders rotate large discs loaded with interchangeable abrasive tools (segments) or pads that grind and polish concrete, natural stone, and terrazzo floors. They accept a variety of abrasives for different degrees of material removal, from stripping off coatings to generating a high-sheen finish. Their wide head grinds more surface area than handheld concrete and masonry grinders. These walk-behind and remote control machines are used to maintain floors and prepare them for recoating in industrial settings such as warehouses, distribution centers, and manufacturing facilities.
