Arc Abrasives 10864AF Flap Disc 4.5x7/8 in Type 29 60 Grit

Product Description

The ARC ABRASIVES 10864AF is a Type 29 angled flap disc designed for general-purpose grinding and blending on metal and composite surfaces. Measuring 4.5 inches in diameter with a 7/8-inch arbor hole, it runs at a 60-grit abrasive rating suited for aggressive material removal with a controlled finish. The cotton backing layer reinforces the abrasive flaps, maintaining disc integrity under sustained load. Fabricators, welders, and metalworkers use this disc for weld cleanup, surface prep, and edge deburring on production and field applications alike.

The 10864AF is well suited for use on mild steel, aluminum, and composite materials in both shop and jobsite environments. The Type 29 conical geometry increases surface contact on flat and contoured workpieces, making it a practical choice for blending welds, removing mill scale, and preparing surfaces before coating or inspection. It is sold individually and fits standard 4.5-inch angle grinders.
