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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 29 conical profile increases contact area for efficient blending and grinding\u003c\/li\u003e\n  \u003cli\u003e60-grit abrasive rating for aggressive stock removal with moderate surface finish\u003c\/li\u003e\n  \u003cli\u003eCotton backing adds structural strength and durability under load\u003c\/li\u003e\n  \u003cli\u003e4.5-inch diameter with 7\/8-inch arbor fits standard angle grinders\u003c\/li\u003e\n  \u003cli\u003eCompatible with mild steel, aluminum, and composite substrates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose replacement flap disc for standard 4.5-inch angle grinders accepting a 7\/8-inch arbor.
