Single disc grinder ideal for surface preparation in large areas. Variable speed gives the operator greater performance in situations such as removing the adhesive coating when excessive speed generates heat, making removal difficult.

The tools are mounted on a floating disk fixed on an anti-shock joint that guarantees maximum reliability. RTK 650 is the only single-disc grinder equipped with an electric piston that allows the regulation of the tool pressure and to stabilize the machine to prevent the operator from unexpected reactions during sanding operations.

The result is a unique, new machine, perfect for a wide range of jobs on floors. RTK 650 is equipped with vibration dampers both on the smoothing disk and on the sensitive parts of the sander in order to minimize vibrations on the operator and on the machine itself. RTK650 is a heavy-duty machine that offers exceptional performance, intelligent ergonomics for easy handling.
