3M 566A Zirconia Aluminium Flap Disc, 125mm, Fine Grade, P120 Grit, PN65026

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.

Run straight onto a right angle grinder, are a one-step system for grinding and blending. The 566A is a great disc when durability is required for medium-weight grinding, small weld removal, finishing and surface preparations. There are various grades of grain available;

• 153-498 is a flat 3M 566A flap wheel with a P40 grain
• 153-599 is a flat 3M 566A flap wheel with a P80 grain
• 153-583 is a flat 3M 566A flap wheel with a P120 grain

• 153-549 is a rounded 3M 566A flap wheel with a P120 grain

• 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

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:

• Building and construction industries
• Automotive engineering and manufacturing
• Ship and boat manufacturing
• Metal fabrication
• Home DIY

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.

• P40 Grit – Useful when you need to remove heavy stock from a surface.
• P60 Grit – For when you need to remove stock from a surface, but will need to refine the finish.
• P80 Grit – This is for light stock removal and sharping only.

3M is a leading innovator of abrasive technologies, constantly evolving to provide ideal solutions to industrial and commercial applications. With 3M you can be assured of a wide selection of quality products.

Bring a shine back to your metalwork by fitting this abrasive disc from 3M to your angle grinder. It's constructed with overlapping flaps and a self-sharpening alumina-zirconia abrasive to give you a consistent result. The three-dimensional design ensures that the wear is even, so the disc lasts longer. With a P120 grit, it's suitable for cutting, blending and finishing tasks. As it works on all types of metal, it's handy in deburring, deflashing and edge-chamfering applications.

• X-weight cotton cloth backing and resin bond for heavy duty tasks
• Flexibility enables you to work on curved surfaces
• Closed coat ensures efficient stock removal

• Automotive industry
• Metal fabrication
• Machine building
• Construction industry

This disc can handle speeds up to 12,000rpm, to help you whizz quickly through your work.
