Bosch PRO Zirconium Abrasive Flap Disc

This Bosch PRO X571 Zirconium Abrasive Flap Disc is a 115mm diameter disc with a 120g (fine) grit, ideal for fine finishing, light blending, and achieving smooth surface profiles on metal prior to painting or inspection. The fine 120g grit removes minimal material while producing a refined, consistent finish — making it the right choice for final-stage surface work or where tight tolerances and clean aesthetics are required. The 115mm diameter suits compact angle grinders used for detailed and close-quarter work. Despite its fine grit, the aluminium oxide and zirconia grain fusion still delivers up to 1.5x faster performance than the Bosch X431. The X-cloth backing ensures stability and control throughout each pass. Features and Benefits: • Fine 120g grit for smooth finishing and pre-coating surface preparation • Advanced grain fusion of aluminium oxide and zirconia for efficient performance, 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: 120g Bore: 22.23mm
