Grain: Aluminium Oxide
The PS 33 K by Klingspor is always the right choice for sanding on Varnish, Timber, Paints & Filler.
The grain is made of aluminium oxide, an abrasive grain that is exceedingly hard and tough. Aluminium oxide is marked by its crystalline characteristics and irregular shapes, which allow for a high removal rate. The grit is applied with a semi-open coating, which makes it ideal for sanding varnish as well as wood and paint. The greater chip clearance created by this coating allows the abrasive dust to dissipate, keeping it from accumulating and ultimately clogging the abrasive disc PS 33 BK. This quality contributes to an extended service life of the abrasive disc.
