ToolKing Flap Disc 125mm 5 Inch (40/80/120 Grit) - Pack of 5

Flap discs are the versatile workhorses of surface preparation. Unlike solid grinding wheels, the overlapping flaps provide cooler, smoother grinding with consistent finish. This pack gives you three essential grits for complete workflow coverage.

Start with 40 grit for aggressive material removal – weld grinding, heavy rust removal, or shaping work. Move to 80 grit for general surface preparation and blending. Finish with 120 grit for smooth surface finishing before painting or coating.

The flap design means less heat buildup compared to solid wheels, reducing the risk of warping thin materials or affecting heat-treated steel. The flexible flaps conform to contours better than rigid discs, making them ideal for automotive bodywork and fabrication.
