Product Description

3M presents the 566A Zirconia Aluminium Flap Disc, model 3M556A B61794, engineered for demanding grinding and blending operations in industrial settings. This disc features a robust zirconia aluminium abrasive material, which self-sharpens during use while providing superior cutting power and longevity compared to conventional aluminium oxide discs. The 125 mm diameter ensures broad coverage, enabling efficient material removal and optimal finishing.

Medium grade grit offers a versatile solution for tasks that require both aggressive removal of paint, varnish, or welds and a smooth surface finish. Its advanced abrasive layer maintains consistent sharpness and delivers excellent durability, reducing the frequency of replacements. The flap design, coupled with a strong polyester-cotton backing, results in flexible yet resilient performance when used on medium to high-pressure grinding and finishing applications.

An innovative quick change attachment system allows users to install or remove the disc swiftly without the need for additional hand tools, saving valuable time in production and maintenance workflows. The disc supports a maximum safe operating speed of 12250 RPM, making it suitable for use with popular right angle grinders operating in industrial, metal fabrication, and repair facilities. The 22 mm centre hole diameter is compatible with most standard grinder interfaces, simplifying integration into existing tool inventories.

Each disc is supplied individually, making it ideal for maintenance crews and production lines requiring precise stock management. Practical applications span shipbuilding, boat construction, heavy manufacturing, residential repairs, and metalworking, where reliability, consistent performance, and easy handling are critical.

Optimal storage involves keeping discs flat in a dry, thermally stable location to prevent weakening through moisture or temperature fluctuations. The 3M 566A series is trusted by professionals for rapid blending, weld removal, finishing, and surface preparation.
