Bosch PRO X Lock Zirconium Abrasive Straight Flap Disc

This Bosch PRO X571 Flap Disc is a 115mm diameter disc with a coarse 40 grit, designed for aggressive stock removal and rapid material stripping on metal surfaces. The coarser grit makes it an ideal first-pass disc when tackling welds, rust, or heavily scaled steel. Performing up to 1.5x faster than a Bosch X431 Flap Disc, the PRO X571 is engineered for speed without sacrificing control. The advanced grain fusion of aluminium oxide and zirconia retains sharpness even in hardened steel, prolonging disc life and maintaining cutting performance throughout the job. The durable X-cloth backing provides a stable grinding platform, allowing you to work confidently at pace. Compatible with X-Lock fitment for tool-free disc changes, as well as standard nut-and-thread angle grinders.
