In daily use

The PS 21 FK excels in woodworking, paint preparation, and filler sanding. Its semi-open grain distribution prevents build-up when working on resinous woods or old varnish, maintaining a consistent cut rate from first to last stroke. The heavy F-paper backing resists tearing on edges and profiles, while the full synthetic resin bond keeps grains firmly anchored under high heat and pressure. For painters, carpenters, and cabinet makers, this disc reduces downtime and improves surface quality before finishing.
