The Bosch PRO R574 Metal Fibre Sanding Disc is built for metalworkers who demand consistent, long-lasting performance. Lasting up to 1.7x longer than the Bosch R444 Fibre Disc, it's engineered for repeated stock removal from mild metals and hardened steel alike. Self-sharpening zirconia grains stay sharp throughout the disc's life, delivering reliable material removal session after session. The tough vulcanised backing provides a stable grinding platform, letting you work faster without sacrificing finish quality — reaching flat surfaces that a flap disc simply cannot access. Available in 115mm, 125mm, and 180mm diameters across a range of grits from 24g to 120g, with a 22.23mm bore to fit standard locking nut angle grinders. A suitable backing pad is required.
