What is an Angle Grinder Flap Disc?

A flap disc is a type of grinding wheel that is fitted to an angle grinder. It consists of a number of thin metal discs (flaps) attached to a central metal hub. The flaps are flexed as the disc rotates, providing a high degree of grind metal contact area and causing the material to be ground away. This makes flap discs ideal for heavy stock removal and removing large amounts of material quickly and efficiently.

Angle grinders use a flap disc to cut and sharpen metal. The angle grinder’s grinding wheel is powered by an electric motor that speeds up the disc. Flap discs are used in various ways, including for drilling holes or cutting various materials. Angle grinders can also be equipped with diamond blades for precision work on jewelry pieces or other small items requiring an extremely sharp cutting edge.

Types of Angle Grinder Flap Disc

There are main types of an Angle Grinder Flap Disc:

1. Flat Discs (or Type 27 discs):

Flat discs are the most common flap disc type and can be found in a range of sizes. Flat discs feature a flat, rectangular surface that is approximately 1/4″ thick and 3-5 inches wide. The disc’s shape makes it easy for the grinding wheel to cut through all types of metal, including aluminum, stainless steel, or copper. They have a flat shape, circular irregular shape, and are ideal for grinding and sanding metal.

2. Conical Discs (or Type 29 discs):

Conical discs are made from a variety of materials, including aluminum material or steel. Conical discs feature two different kinds of grooves that make it much easier for the cutting wheel to cut through metal: one is located in front and another at the back.

Most conical disc grinders have five blades on each side, but some models also include three or four more blades so they can be used with smaller pieces of metal. Cone-shaped cutting discs are designed for precision work on the delicate metal surface and have a conical shape that allows them to fit into tight spaces and provide a high degree of accuracy.

3. Zirconium Flap Discs (Type 40 discs):

Zirconium flap discs are a high-quality option that is suitable for angle grinding because of their unique features. For example, zirconium flap discs are made from zirconium oxide, a metal that is extremely hard and non-corrosive. This makes zirconium flap discs the perfect choice for sharp edge grinding because they can withstand high speeds and temperatures without wearing out or becoming damaged.

4. Compressed-shaped Discs (Type 41 discs):

Compressed-shaped discs are made from a variety of materials, including aluminum or carbon steel. Compressed-shaped discs have a unique shape that is not found in other types of flap discs. Their shape allows them to fit into tight spaces and provides a high degree of accuracy. They are also extremely durable and can withstand high speeds and temperatures without damage.

There are a few factors you need to consider when choosing the right flap disc for your angle grinder:

Type of Work Material:

Some discs are better suited for particular types of materials. If you will be working with a variety of popular materials, it is essential to choose a disc that can be used with multiple types of materials.

Size of Flap Disc:

Flap discs are available in a variety of sizes. It is crucial to choose a disc that is the right common size for the project you will be working on. Larger discs are better suited for larger projects, while smaller discs are ideal for precision work.

Type of Flap Disc:

There are three main types of flap discs: flat discs, conical discs, and zirconium flap discs. Each type of disc has unique features that make it better suited for specific projects. Therefore, it is important to choose a grinding disc that is the right type for the project you will be working on.

What is the difference between a flap disc and a flap sanding disc?

An abrasive flap disc is an abrasive wheel with flaps, which are steel discs bonded to ceramic backing flanges. The flap disc grinder can be used on angle grinder polishing drums and weld grinding wheels for sanding wood, concrete pavement, or cut tiles.

How are flap discs effective for grinding stainless steel surfaces?

The flap disc design makes it very effective in grinding stainless steel irregular surfaces because of its high-tech abrasive flange. Also, the disc retrieves abrasive grinder grits quickly and evenly to minimize over-grinding of insulation wire braid (rope).

Why is aluminum oxide the best abrasive grit flap disc?

Aluminum oxide abrasive grit is the best choice for conical flap discs because it has a high finer grit mesh flap density and does not clog easily.

How long can flap discs be used?

Flap disc grinder abrasive product lighter grits are not reusable, so they should be replaced when the flaps become worn or clogged.
