Always choose a Flap Disc at least ONE GRADE COARSER than the Fibre Disc being used to obtain a similar finish with the same aggression:
FIBRE DISC P100 P80 P60
FLAP DISC P80 P60 P40
How to Use:
Address the flap disc at an angle of 30 to the workpiece for stock removal.
Lessen the angle for the final blending passes. Let the flap do the work, use less working pressure than for angle grinding discs for best grinding performance and flap disc life.
From Factory:
KSEIBI Flap Discs are designed for use on portable grinders and sanders, and are increasingly popular as an alternative to abrasive fiber discs. They complement the use of depressed center grinding wheels, and are the preferred option on light gauge sheet metal or stainless steel where finish is important.

Description
Flap discs are used in heavy stock removal, often weld removal. They outperform Resin Fiber Discs due to their increased lifetime and last twice as long as Aluminum Oxide discs. To achieve a finish equivalent to a Resin Fiber Disc, always use a flap disc one grit coarser. e.g. If the operator is running a 60 grit Resin Fiber Disc, try a 40 grit flap disc. This 40 grit flap disc is made with Zirconia Alumina grain, which is ideal for stainless steel and metal applications while still working well with non-ferrous applications. The Type 29 angled face allows for 90% of the abrasive material to be in contact with work surface, yielding maximal grinding surface area for greater ease, effectiveness and speed. We use a high quality backing plate to help absorb vibration. Specific suited applications include: weld blending, removing weld slag, deburring, edge blending, surface conditioning and general metal fabrication. 'Jumbo' or 'High Density' flap discs usually contain 30-60% more surface area for grinding.4. 5pc 4.5" Flap Grinding Disc Assorted Pack (40, 60, 80, 120, 180 Grit)
