Innovatively Designed Flap Discs

A flap disc is created using three basic components — a backing plate, an adhesive material and a series of abrasive flaps. What distinguishes flap discs from other abrasive wheels and discs used in grinding and cutting aluminum is rather than being a circular-shaped flat sheet of coated abrasives, it features overlapping flaps capable of producing a more even and consistent abrasive wear on a larger surface area. Variables when choosing the right flap discs for grinding, deburring, sanding and blending include shape, backing material, density and grit.

The unique design of flap discs lends itself primarily to right angle grinding applications, providing exceptionally uniform grinding results even as the flaps begin to erode with long-term use. The fact flap discs are capable of deburring and finish-cleaning surfaces while simultaneously offering the added benefit of reduced production and labor costs. Types of backing materials include fiberglass, aluminum and plastic depending on your needs.

Flap discs can be specifically configured for:

·         Blending and smoothing finishing work on flat surfaces

·         Heavy stock removal on contoured and edge work

·         Precision performance on smooth or uneven surfaces

·         Fast cutting on carbon and mild steel materials
