This Bosch EXPERT X551 Flap Disc is supplied as a single 115mm disc in a fine 120 grit — the finest option available in the 115mm range, designed for surface finishing and final-stage preparation on mild-steel and stainless-steel workpieces. The 120 grit removes far less material than coarser options but delivers a much smoother, cleaner surface, making it the right choice for finishing welds, refining surfaces prior to painting or coating, or achieving a polished aesthetic on stainless steel. Use it with your small angle grinder for precise, controlled results. The straight shape, stable backing, and strong abrasive grains maintain consistent performance right through to the last pass.
