Flap discs are versatile grinding and finishing tools with three main components - backing plate, adhesive, and abrasive flaps. The flaps wear during use continually exposing new abrasive grain. The different variations of the components provide a variety of applications, ranging from heavy stock removal to blending to finishing. Flap discs are designed for portable grinder applications and can combine the 2-step stock removal and finishing operations of depressed center wheels and fiber discs into one operation.

- Flexible plastic backing plate adds conformability and is quickly, easily trimmable
- Polyester cotton backing combination for good cut rate and finishing
- Good choice for soft metals to hard to grind stainless and carbon steel, medium girt cleaning, detailing and finishing
- Angled, polyester/cotton flaps provide greater surface contact and are the best choice when speed of job completion and stock removal are primary considerations, may be used on contour and edge work
- Their fiberglass/resin backing plates are the most popular plate configuration due to high strength, light weight, ability to absorb vibration and operator comfort
