This Bosch PRO X571 Zirconium Abrasive Flap Disc is a 125mm diameter disc with a 40g (coarse) grit, delivering aggressive, fast stock removal for heavy grinding and weld dressing tasks on metal. The 125mm diameter is one of the most widely used sizes in professional metalworking, offering an excellent balance between coverage and manoeuvrability. The coarse 40g grit is ideal for rapid material removal, heavy weld grinding, and surface preparation on both mild and hardened steel. The advanced zirconia and aluminium oxide grain fusion drives performance up to 1.5x faster than the Bosch X431, and the X-cloth backing keeps the disc locked in a stable grinding position for efficient, consistent results.
