This Bosch PRO X571 Flap Disc is a 125mm diameter disc with a coarse 40 grit, built for heavy-duty stock removal and aggressive surface preparation on metal. The larger 125mm diameter covers more surface area per pass, helping you get through demanding tasks more efficiently. Up to 1.5x faster than a Bosch X431 Flap Disc, this disc excels where speed of material removal is the primary requirement. The advanced grain fusion of aluminium oxide and zirconia retains its sharpness even in hardened steel, maintaining high cutting performance for longer. The durable X-cloth backing provides excellent stability during grinding, reducing fatigue and improving finish consistency even at pace. Compatible with X-Lock angle grinders for quick, tool-free disc swaps, as well as standard nut-and-thread grinders.
