The Hydra Sand attachment utilizes six 125mm (5 inch) pads mounted to a thick steel plate and will mount on to any rotary sander. The six sanding pads provide maximum sanding performance and longer runs between abrasive changes. Pads are adhered to firm red foam, which allows for increased stock removal and a superior levelling ability. The added weight of the heavy gauge steel adds considerable strength and durability and provides for faster removal of material from the floor. Added strength and performance is provide by the rugged assembly, which included steel encased bearings. The raised shaft of the bearing allows for quick and easy pad removal. An isolator/dampener provides superior user handling and reduces machine and operator motions from being transferred to the floor, this This helps to prevent gouging on uneven floor surfaces.
