How Much Do You Know About Flap Disc?

Have you ever heard of a kind of abrasive tool called flap disc? Do you know what it is used for and its product performance? Do you understand its working principle?

Product performance of flap disc

The flap disc is mainly installed on handheld electric tools to polish various metal and non-metal parts such as welding seams, burrs, chamfers, surface rust removal, surface polishing, etc. Compared with fixed abrasive resin grinding wheels, it can complete the polishing process in one step, shorten operation time, save polishing costs, improve grinding efficiency, has a strong self-sharpening ability, wind-cooling cooling will not damage the surface, easy to control the surface quality, reduce operator fatigue, increase machine life and other characteristics. Therefore, it is widely used in various industries in the manufacturing industry.

Application scope of flap disc

The flap disc is used for grinding and polishing of iron and non-ferrous metals, stainless steel, stone and plastic, as well as welding seams, scars, and edge burrs of stamping parts. It can be used interchangeably with resin bowl-shaped grinding wheels. The flap disc has the advantages of high elasticity, good self-sharpening, high grinding efficiency, good heat dissipation, low noise, long service life, etc.

Advantages and uses of flap disc


The flap disc has good elasticity, good heat dissipation, low noise, and can replace resin bowl-shaped grinding wheels. It has strong elasticity, high tensile and bending strength, low noise, and is suitable for grinding welding seams and burrs of stamping parts inside the box.


The flap disc can be used in the shipbuilding, automotive, aviation, machinery, instrument, bridge and building industries, as well as for various surface rust removal, paint removal, burr removal, and welding seam grinding of metal and non-metal materials in furniture. It can be assembled and used on electric and pneumatic tools, and used for grinding and polishing of various stainless steel and carbon steel structural parts. It is particularly suitable for polishing and processing of stainless steel surfaces, metal chamfers, concave and convex surfaces, welding seams, etc., especially in the polishing and processing of shipbuilding, aviation, and large-scale machinery equipment.
