Faithfull Aluminium Oxide Flap Disc 115 x 22mm 120 Grit FAIFD115A120

The Faithfull Aluminium Oxide Flap Disc is designed for efficient grinding and surface preparation of mild steel, carbon steel, and alloys. It features a lightweight fiberglass backing that reduces vibration while enhancing strength and durability. The layered flap design comprises 72 flaps that enable fast stock removal with minimal risk of gouging or discoloration. With a 115 mm diameter and 22 mm bore, this disc is suited for angle grinders and is described as having a conical shape optimized for grinding on contoured surfaces at 15-25 degrees. It is noted for a longer life—up to about 30 times longer than fibre discs—and self-sharpening flaps that contribute to fewer disc changes. The disc is cooler and quieter than typical grinding discs, providing controlled and consistent surface finish on suitable metals.
