The sanding sheets from Finixa feature a paper backing and measure 23 x 28cm. The self-sharpening Blue Fired aluminum oxide grain ensures a longer lifespan for the sanding sheets. The abrasive grain is bonded so that the sharpest side of the grain is always in contact with the surface, increasing sharpness and speed during sanding. Thanks to the red stearate layer, sanding dust will adhere less quickly between the grains, making the sandpaper last longer. These sanding sheets are ideal for easily sanding parts and small surfaces in a cost-effective way. The sandpaper can be easily torn or cut to the desired size.
