Floor grinders renew concrete surfaces

Stow’s new DFG Series floor grinders remove grease, dirt and glue residues from concrete floors with two counter-rotating discs grinding across a work area of 24 by 12 inches. The three models in the line range in weight from 250 to 300 pounds and are powered by Honda gas or electric motors. The grinders feature a heavy-duty spur gear transmission and a belt cover that provides space to store up to 300 pounds of external weight. A 3-inch dust port helps keep the work area clean and ergonomic handles maximize control and minimize fatigue. The grinders will take both General and Edco attachments.
