This Bosch PRO X571 Zirconium Abrasive Flap Disc is a 115mm diameter disc with an 80g (medium-fine) grit, designed for tasks requiring a finer finish while still delivering efficient material removal on metal. The 80g grit is well suited to surface preparation, blending, and finishing work where a smoother surface profile is needed ahead of coating or inspection. The compact 115mm diameter fits neatly onto smaller angle grinders for precise, controlled use. Powered by the advanced aluminium oxide and zirconia grain fusion, this disc works up to 1.5x faster than the Bosch X431, and the robust X-cloth backing keeps it firmly positioned throughout the grind. Features and Benefits: • Medium-fine 80g grit for finishing, blending, and refined surface preparation • Advanced grain fusion of aluminium oxide and zirconia for fast stock removal, even on hardened steel • Durable X-cloth backing for a stable grinding position with no loss of finish • 22.23mm bore compatible with standard locking nut angle grinders Specifications: Diameter: 115mm Grit: 80g Bore: 22.23mm
