The Bosch PRO X571 Flap Disc in 125mm diameter with a 40-grit abrasive delivers maximum cutting aggression across a wider grinding surface, making it the ideal choice for heavy-duty stock removal, weld dressing, and tackling large areas of hardened steel quickly and efficiently. The larger 125mm diameter increases coverage per pass, reducing the time needed on bigger workpieces. Combined with the advanced grain fusion of aluminium oxide and zirconia, this disc cuts up to 1.5x faster than the Bosch X431 Flap Disc, so you can power through even the toughest material removal jobs. The X-cloth backing provides excellent stability under the higher forces involved in coarse grinding, keeping the disc flat and in control. Fits X-Lock angle grinders with a simple click-on connection and is also compatible with nut-and-thread machines.
