Pegastar 4″ 100×16 Flap Disc for Stainless Steel (20pcs/box)

Made for stainless steel applications, the PEGASTAR flap disc features high-quality ZA (zirconia-alumina) or alumina abrasive grains for excellent durability and cutting-action. Certified to EN13743/MPA standards with a maximum safe speed of ~80 m/s. Fine performance for both stock removal and finishing: 40-grit for aggressive work, finer grits for smoother surface polishing. Backed with resin bond, the disc contours well and resists loading, delivering burr-free finishes and long service life.
