Blue-Kote II High-Density Flap Disc, 4-1/2" Diameter, 7/8" Arbor, 60 Grit, 1 Each

These Zirconium grain discs with a phenolic backing are designed for efficient one-step grinding, blending, cleaning, and finishing. Their thicker construction and larger flaps ensure a 30% to 40% longer lifespan compared to standard flap discs, while providing excellent conformity to curved and irregular surfaces for a consistent finish. The phenolic backing prevents scratching during operation, making these discs ideal for use on 4-1/2" right-angle grinders and suitable for all metal surfaces, whether for blending or finishing on contoured or flat areas.
