Flap Disc

Flap Discs for Blending, Deburring & Surface Finishing

Flap discs are a smart choice when you want controlled removal plus a cleaner finish—often reducing the need to switch between multiple abrasive steps. They’re commonly used for weld blending, edge smoothing, and surface refinement in metalworking and fabrication.

Choose flap discs by grit: coarser for faster blending and cleanup, medium for smoothing, and finer grits for surface improvement and prep.

Best Use Cases

  • Weld blending and cleanup.
  • Edge smoothing and deburring.
  • Surface refinement and finishing steps.

Perfect for use with angle grinders and compatible with steel, stainless steel, aluminum, and more.
