Description Main features and benefits: The zirconium abrasive is particularly suitable for applications requiring high operating pressure and even for medium/high-power cornering grinders. The flap paired arrangement provides better ventilation and improves scrap/waste escape. Wide abrasive surface, constant wear, continuous exposure of new grit, high and even cutting performance. Always use the backing pad for the 165mm-diameter disc. Recommended applications: Deburring, removing welding seams, blunting sharp corners and edges. Work surfaces: Stainless steel, alloyed and unalloyed steel, aluminium, nonferrous metals and alloys, structural steel, cast iron, titanium.
