This Bosch PRO X571 Flap Disc is a 125mm diameter disc with a fine 120 grit, designed for precision finishing and surface refinement on metal. The larger 125mm format allows you to cover more area during final-pass work, making it a practical choice for finishing larger components efficiently. Even at 120 grit, this disc delivers up to 1.5x faster performance than a Bosch X431 Flap Disc, so finishing stages don’t have to slow down your workflow. The advanced grain fusion of aluminium oxide and zirconia maintains sharpness throughout the disc’s life, ensuring a consistent, quality finish every time. The X-cloth backing provides excellent stability during fine grinding work, giving you the controlled, smooth result that finishing demands. Compatible with X-Lock and standard nut-and-thread angle grinders.
