Flap Discs

Flap discs are one of the most common abrasives used in metal fabrication shops around the world. Shop owners and operators rely on them for their versatility, long life and ease of use. Since they are more conformable than other abrasive discs and wheels, operators of every skill level are less likely to damage parts by gouging the metal. While fibre discs grind faster and grinding wheels last longer, they don’t offer the application versatility of flap discs, which leave a finer finish after the grinding step.

3M flap discs are the product of decades of technological innovation and application expertise. We offer both type 27 (flat) and type 29 (conical) flap discs in a range of sizes and attachment systems to fit your angle grinder.

Flap discs are constructed of overlapping abrasive-coated flaps attached to a central hub. As the disc is used, the flaps continually wear away to expose a new layer of abrasive mineral. This allows for a consistent cut-rate and finish throughout the entire life of the disc.

Plus, the gaps between the coated abrasive flaps make them much more conformable than other grinding discs and wheels — making them great for grinding and blending on curves and contours.
