Flap Disc

• The separate flaps each attack the workpiece surface at a slightly different angle, and this varies slightly 

with the tool angle. This avoids the common problem with flat sheets, where they produce repeated 

identical scratches.

•Abrasive wear is distributed more evenly across the flaps and through the length of each flap. Flaps 

wear from their outer ends and the sheet carrier cuts back as the abrasive coating is worn away. The 

wheel remains useful even as the flaps erode. Compared to flat sheets, that are discarded after only a 

small area of the abrasive is truly worn-out, this is a much more efficient use of the abrasive material.

                      

• Angled, durable, Y-weight polyester flaps provide greater surface contact and are the best choice for 

fast stock removal – with significantly enhanced life, grain retention, and fray resistance                    

• The best choice for coarse grit blending, deburring, and stock removal                   

• Their fiberglass/resin backing plates are the most popular plate configuration due to high strength, 

lightweight, ability to absorb vibration, and operator comfort
