Flexible Flap Discs • Zirconium grain, phenolic backing • Pointed flap configuration extending from the backing plate is excellent for accessing tight 90° corners and hard-to-reach areas • Ideal for use on contoured and irregular surfaces • Overlapping flap construction promotes resistance to edge wear • Controlled breakdown of abrasive cloth and continual exposure of new grains allows consistent aggression throughout the disc life Dia.
