Why buyers pick this one

Calcined Abrasive Grains: The heat-treated Aluminum Oxide flaps run cooler and last considerably longer than standard abrasive cloth. They constantly expose new, sharp cutting edges, preventing glazing even on hard stainless steel.
One-Step Finishing: The overlapping abrasive flaps simultaneously grind away heavy material and blend the surface, eliminating the need to constantly switch between hard grinding wheels and sanding pads.
Vibration-Absorbing Backing: Available with durable fiberglass or robust plastic backing pads that consume evenly with the abrasive flaps, reducing operator fatigue and preventing damage to the workpiece.
High-Speed Safety Rated: Engineered to withstand extreme rotational forces up to 15,300 RPM (80 m/s), ensuring maximum safety on standard 4" angle grinders used in harsh industrial environments.
Dedicated B2B Manufacturing: Stop relying on middleman traders. We offer true OEM customization, allowing you to build your abrasive brand with custom grit configurations, private-label center stickers, and robust shrink-wrap packaging.

Overview

Maximize operator efficiency and streamline your abrasive inventory with the premium Flap Discs from Shanghai Daoge Xiaoman Tools Co., Ltd. Designed to replace both a grinding wheel and a resin fiber disc, our flap discs grind and finish in a single step. What makes this 4-inch (100mm) disc exceptional is its abrasive material: Calcined Aluminum Oxide. This high-temperature heat-treated grain is significantly tougher and sharper than standard brown corundum, aggressively removing weld seams, rust, and burrs on carbon steel and stainless steel (INOX) while providing extended disc life. Mounted on a lightweight, vibration-absorbing fiberglass or plastic backing pad, it offers comfortable, gouge-free grinding. Partner with us for massive container-volume sourcing, featuring tailored grit sizes (40# to 120#) and your proprietary brand labels.
