Arc Abrasives 71-10824AF Flap Disc Type 29 40 Grit

Product Description

The ARC ABRASIVES 71-10824AF is a Type 29 flap disc designed for general-purpose grinding and blending on metal and composite surfaces. Measuring 4.5 inches in diameter with a 0.875-inch arbor hole, it fits standard 4.5-inch angle grinders. The disc is built with a cotton backing that adds structural strength and durability through extended use. At 40 grit, it removes material aggressively, making it well-suited for weld blending, surface prep, and stock removal tasks. Fabricators, ironworkers, and general metalworkers are the primary users of this disc in both shop and field settings.

This flap disc is intended for use on mild steel, aluminum, and composite materials in fabrication, manufacturing, and maintenance applications. The Type 29 angle geometry positions the abrasive cloth at an angle to the workpiece, which increases surface contact and improves material removal compared to a flat Type 27 disc. It is sold individually and is well-matched to light industrial and general trades work where a reliable, cost-effective abrasive is needed for routine grinding and blending tasks.
