The PFERD POLINOX Compact Grinding Disc PNER-MW 125-22.23 SiC F is designed for face-down grinding on speed-adjustable angle grinders, making it particularly suitable for processing larger surfaces. The disc features a compressed, non-woven material bonded to a glass-fabric base, providing a high stock removal rate and long tool life. This medium-soft version offers increased edge strength and is well-suited for coarse blending and polishing tasks, especially on edges.
