3M 566A Zirconia Aluminium Fibre Disc, 125 mm, Medium Grade, P80 Grit 1 Per Pack

Attach this flap disc from 3M to an angle grinder when you want to remove old paint, varnish or small welds. Its zirconia-aluminium coating is tough and self-sharpening, so it's an effective grinding and blending solution for wood and metal surfaces. This advanced finish also provides superior durability and a long working life, while the round disc design lets you make quick changes on your grinder or sander without needing hand tools. To keep you stocked up, these discs come in packs of five.

• P80 grit size for medium sanding and grinding applications• Maximum safe speed of 12,250 RPM (revolutions per minute) for fast action• Polyester-cotton backing provides strength and flexibility• Disc diameter of 125mm gives you a wide area for more efficient performance

• Shipbuilding and boat construction• Residential repairs• Construction industry• Metalworking

To ensure optimal performance, store these discs lying flat in a dry, thermally stable location. Damp and frost can weaken the discs over time, while wide temperature fluctuations can create instability in the fibres.

Introducing the 3M™ 566A, this flap wheel 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.

Flap discs are a type of power tool accessory that can be used in conjunction with angle grinders to grind, blend and remove excess material, depending on what the task is that they are being used for. Flap discs are available in different grit sizes and each grit size will be more or less suitable for removing excess material from welds or removing rust, descaling, preparation of surfaces for painting or polishing and other surface finishing applications. They are most commonly used in:

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.

In order to keep them in ideal condition, flap discs should be stored flat, avoiding damp and frost or wide temperature variations.
