2" CURVED QUICK CHANGE FLAP DISCS FOR ALUMINUM – 1 PIECE

Benchmark Abrasives 2-inch curved flap discs for aluminum are designed for fast grinding, weld blending, deburring, and surface preparation on aluminum and other soft, non-ferrous metals. The premium abrasive grain provides an aggressive, consistent cut, while the specialized stearate coating helps reduce loading, clogging, and material buildup.

Unlike conventional flap discs that can quickly gum up when used on aluminum, the stearate treatment liquefies slightly as heat develops during grinding. This creates a protective barrier across the abrasive flaps, helping prevent aluminum particles from sticking to the disc. The result is cleaner cutting, longer disc life, and less downtime replacing loaded abrasives.

The curved flap design provides improved access to fillet welds, inside corners, contours, and other hard-to-reach areas. Its compact 2-inch diameter offers excellent control on smaller components and detailed fabrication work, while the quick-change attachment allows operators to replace discs in seconds without tools. These curved mini flap discs are ideal for fabrication shops, automotive applications, maintenance work, and production environments.
