The 3M 577F Flap Disc delivers aggressive material removal with a 40-grit YF-weight abrasive cloth, making it well suited for heavy grinding, weld blending, and stock removal on metal surfaces. The 4-1/2 inch diameter with a standard 7/8 inch arbor hole fits most common angle grinders for easy setup and use.
Designed for demanding industrial and fabrication applications, the 577F construction resists loading and maintains a consistent cut throughout the life of the disc, helping reduce downtime and improve productivity on the job.
