An optimized system for perfectly smooth, homogeneous surfaces without dust. Highest quality with less effort. The best solution for medium and large surfaces, designed for one, two or more operators for the machining of rectilinear surfaces and curves, characteristic of the marine and composite world. The tool shall be connected to a professional vacuum cleaner equipped with 30 or 38 mm flexible hose. Dust is sucked through special hole pattern, corresponding to the one of the abrasive when using the pre-drilled traditional abrasive, or across the entire surface, using the net abrasives.
