Flap discs combine overlapping abrasive flaps with a backing plate. They grind and finish in a single operation, making them ideal for smoothing welds and shaping metal. Choose the appropriate grit for the surface finish you require.

What are flap discs used for?
Flap discs are abrasive tools used with angle grinders for grinding, blending, and finishing metal, wood, and plastic surfaces. They are ideal for weld removal, surface preparation, deburring, and rust removal, offering a smoother finish than traditional grinding discs.
What is the difference between flap discs and grinding discs?
Flap discs use overlapping abrasive flaps that wear away evenly, exposing fresh grit for consistent cutting. This provides a cooler, smoother, and more controlled finish, making them ideal for blending and finishing work. Grinding discs are more aggressive and suited for heavy material removal but tend to leave a rougher surface.
How do I choose the right flap disc for my application?
Consider the following:
Grit size:
Coarse (40–60 grit) for fast material removal
Medium (80 grit) for blending
Fine (100+ grit) for finishing
Disc shape:
Flat (Type 27) for surface grinding
Conical (Type 29) for aggressive stock removal and edge work
Material type:
Zirconia for stainless steel and long life
Aluminum oxide for general purpose
Ceramic for fast, high-pressure grinding on hard metals
Choose the disc diameter to match your grinder (e.g. 115 mm, 125 mm) and always follow the RPM limits for safety.
