Flapper 4.5" 120-Grit

Achieve ultra-smooth finishes and precise surface blending with the Home Advantage 4.5" 120-Grit Flap Disc (SJZFD120). Designed for high-speed use on standard 4-1/2" angle grinders, this premium grinding and finishing disc features durable zirconia alumina grain flaps arranged in an overlapping fan pattern. The fine 120-grit profile is specifically formulated for light weld blending, deburring sheet metal, cleaning up surface oxidation, and pre-paint prep without gouging the workpiece. Engineered with a rugged fiberglass backing plate, it cushions operation, dampens hand vibrations, and ensures consistent cut rates across structural steel, stainless steel (inox), and non-ferrous alloys.

Key Features:

• Fine 120-Grit Performance: Excellent for surface preparation, fine blending, scratch removal, and edge cleaning without aggressive material removal.

• Self-Sharpening Zirconia Alumina: Continuously fractures to expose fresh cutting edges, running cooler and lasting significantly longer than standard aluminum oxide discs.

• Vibration-Damping Fiberglass Backing: Rugged multilayered fiberglass plate absorbs machine chatter and protects workpiece surfaces from accidental marring.

• Standard 4-1/2" Profile: Engineered to mount seamlessly on standard 4.5-inch pneumatic and cordless/corded electric angle grinders.

• Versatile Multi-Metal Usability: Optimized for stainless steel, carbon steel, sheet metal, cast iron, and aluminum finishing jobs.
