3M 566A Zirconia Aluminium Flap Disc, 125mm, Coarse Grade, P40 Grit, PN65026

Introducing the 3M™ 566A, this flap disc provides a versatile one disc system that features self-sharpening alumina-zirconia. This abrasive is able to provide better longevity and increased cutting power over aluminium oxide. The strong polyester-cotton backing offers great flexibility and supports a fast cut on medium to high pressure grinding and finishing applications.

• Run-on a right angle grinder 566A discs are a one-step system for grinding and blending
• Alumina zirconia self-sharpens and provides extended life and more cutting power than aluminium oxide
• Strong, Y-weight polyester-cotton backing offers flexibility and supports fast cut on medium to high pressure grinding and finishing applications
• Quick change disc simplifies disc changes and does not require hand tools

Run straight onto a right angle grinder, are a one-step system for grinding and blending. The 556A is a great disc when durability is required for medium-weight grinding, small weld removal, finishing and surface preparations.

While both discs can be used for wood and metal surfaces, flap discs are better suited for use with metal. Abrasive discs are better at removing material from a surface, but for grinding metal surfaces, flap disc presents a more durable and long-lasting solution. They even have some advantages over grinding wheels in that, while they may not remove metal as aggressively, they are slightly safer to use and produce less sparks.

Flap discs are designed to be used with hand-held equipment such as angle-grinders, to be moved over a surface or medium that needs to be sanded or polished. Flap wheels were originally designed to be used with a static machine such as a fixed buffing machine, where the medium is used against the belt. However, flap wheels can also be used on handheld rotary tools such as electric drills. A flap wheel strikes a surface in a less regular way that a flap disc, meaning there are less uniform scratches, which is desirable particularly for metal buffing and polishing. They also last longer than conventional discs as the flaps wear from the outside in, rather than consistently across a disc surface. Conventional flap discs, however, may present a more cost-effective solution for less specialized applications.

Flap discs should be stored flat, avoiding damp and frost or wide temperature variations.
