Bosch PRO X LOCK R574 Fibre Sanding Disc 125mm

The Bosch PRO X-LOCK R574 Fibre Sanding Disc is designed for metalworkers who demand consistent, reliable performance when grinding mild metals and hardened steel. Lasting up to 1.7x longer than the Bosch R444 Fibre Disc, the R574 is built for enduring use and repeated stock removal without compromise.

At its core, the R574 uses self-sharpening zirconia grits that maintain cutting performance over time, paired with a tough vulcanised fibre backing that keeps the disc stable during use. This stability allows you to work faster and achieve a consistent finish — even on flat surfaces where a flap disc simply won't reach.

Compatible with both X-Lock and standard nut-and-thread angle grinders, the R574 fits easily into your existing setup. Available in grit sizes from 24g to 120g to suit a range of metalworking tasks.
