FLAP DISCS Trico’s Flap Discs are intended for grinding with the use of manual grinding machines at a maximum speed of 80m/s. They are distinguished by high durability, low noise levels, smoother grinding, simple use and high grinding efficacy. They can be used for basic grinding, fine grinding of welds, polishing, finishing of edges, surface treatment, cleaning of alloys, etc. When switching to another material (metal, wood, plastics) disc quality need not to be changed, since the difference in their grinding effects may only be noticed after a longer period of use. A type discs, which are manufactured of emery cloth coated with aluminium oxide grains, should be used to finish aluminium, coloured metals, softer alloys, low-alloy steel, plastics and wood, while Z type discs, which are made of emery cloth coated with zirconium Al. oxide grains are intended for the surface treatment of alloys, tough coloured metals and high-alloy, heat-resistant, consolidated steel.
