This Bosch PRO X571 Flap Disc is the 115mm diameter, 80 grit variant — a medium grit option that blends solid stock removal with a cleaner surface finish, suitable for smoothing welds, removing surface rust, and intermediate metalwork finishing. Up to 1.5x faster than a Bosch X431 Flap Disc, the PRO X571 uses an advanced grain fusion of aluminium oxide and zirconia to maintain cutting efficiency even on hardened steel. The durable X-cloth backing holds the disc stable during use, helping you achieve consistent results at speed. The 22.23mm bore is compatible with standard locking nut angle grinders.
