WerkMaster™ has developed a patented proprietary technology that is used on all the Facility Maintenance and Floor Finishing Machines. The Octi-Disc™ Technology delivers superb results and it is unbelievable! How does it work? The Octi-Disc™ technology utilizes eight independent polishing heads that operate collectively, allowing a smooth, even shine or grind on any type of surface, from concrete to hardwood to marble and granite. Even better, since the surface preparation equipment use eight heads instead of one, they spin at a much higher velocity. This means more revolutions per minute, and more RPMs, which means more raw grinding, sanding, polishing, edging, cleaning and buffing power!
