This Bosch PRO X571 Flap Disc is a 115mm diameter disc with a fine 120 grit, ideal for finishing passes and surface refinement on metal workpieces. The finer grit removes less material per pass, making it the go-to choice when a smooth, clean surface result is the priority. Despite its finer grit, it still delivers up to 1.5x faster performance than a Bosch X431 Flap Disc, so you won’t be waiting around during finishing work. The advanced grain fusion of aluminium oxide and zirconia maintains enduring sharpness even on hardened steel, ensuring consistent results throughout the disc’s life. The X-cloth backing provides a stable, controlled grinding position, perfect for the precision required at the finishing stage. Compatible with X-Lock angle grinders as well as standard nut-and-thread machines.
