Abrasive Flap disc


Klingspor technology at its best

Since their market launch, the Klingspor abrasive flap disc has successfully taken the place of the grinding disc in many areas of surface finishing. The performance of the abrasive flap disc, with its fan-shaped radial arrangement of cloth grinding flaps, far exceeds that of other abrasive products.

Klingspor abrasive flap discs are made of zirconia alumina coated flaps fastened to glass fibre-reinforced or plastic backing plates. The even arrangement of the flaps guarantees high flexibility, constant high grinding performance and low vibrations.

Abrasive Flap Discs


Product structure

The three abrasive flap disc components are perfectly integrated to achieve maximum performance.

1. Grinding flaps

Klingspor has developed special coated abrasives for its abrasive flap discs. The grinding tool is perfect for use with high speed angle grinders (80 m/s) and corresponding applications. This ensures top grinding performance and long service life.

2. Backing plate

Klingspor uses two different backing plate types to produce abrasive flap discs. The first one is the most popular on the market made of glass fibre; the second one is made of plastic.

3. Glue

The glue (adhesive) is the joint between the backing plate and the grinding flaps. It ensures that the grinding flaps cannot come off the backing plate if used properly. It also ensures safety far above the guidelines of the oSa directives and the EN 13743 safety standard.


The convex abrasive flap disc grinds a narrower surface than the flat abrasive mop disc. The more selective use of the convex disc achieves a greater stock removal rate per time unit as compared to the flat mop disc. The convex abrasive flap disc is particularly suited to working on edges and welded seams. The flat disc is primarily used for flat and surface grinding.

Coated abrasives

Compared to belt applications the coated abrasives for abrasive flap discs withstand much higher loads. On the one hand, the cutting speed of abrasive mop discs is approx. 2 to 2.5 times faster than the cutting rate of a belt application, on the other hand the backing must wear down to ensure that new, unused grit is used.

Klingspor has developed special coated abrasives specifically for this product group. These are developed specifically for high powered angle grinders (80 m/s) and ensures top grinding performance and long service life.
