Arc Abrasives 10825FF Flap Disc 4.5x7/8 in Type 27 60 Grit

Product Description

The ARC ABRASIVES 10825FF is a Type 27 flap disc designed for general-purpose grinding and blending on a range of common materials. Measuring 4.5 inches in diameter with a 7/8-inch arbor hole, it fits standard angle grinders used daily in fabrication, welding, and metalworking shops. The disc runs at 60 grit, making it well suited for stock removal, weld blending, and surface conditioning where a medium-aggressive cut is needed. Cotton backing reinforces the abrasive flaps, adding structural strength and durability through the full life of the disc.

This flap disc is intended for use on mild steel, aluminum, and composite materials in both shop and field environments. Fabricators, welders, and metal finishing tradespeople reach for this disc when they need a reliable, consistent cut without switching tools. Its Type 27 flat profile keeps the grinding surface flush against flat workpieces, making it a practical choice for flat stock, plate, and structural steel applications.
