What is a type 27 flap disc?

A type 27 flap disc is an important abrasive tool that is used in various industrial applications for finishing and polishing surfaces. In simple terms, it is a grinding wheel that is made up of layered abrasive flaps or pieces that are assembled onto a central hub. These flaps consist of abrasive grains that are firmly bonded to a backing material, thus creating a disc-shaped structure.

The type 27 flap disc is designed for use on angle grinders and is often used in metalworking and automotive industries. The disc is constructed with a depressed center which allows it to maintain a low profile when working on curved surfaces or edges. The design of this disc ensures that the abrasive flaps are able to contour to the shape of the workpiece, enabling it to achieve better finishes on concave and convex surfaces.

One of the benefits of the type 27 flap disc is its versatility. This tool is able to handle a wide range of grinding and finishing tasks, including removing rust, weld spatter, and scale from various metals. Additionally, it is suitable for deburring, blending and finishing welds, and polishing surfaces. The disc is available in different sizes, grits, and materials, making it ideal for various applications.

In terms of safety, type 27 flap discs are designed to minimize the risk of accidents. They are constructed with a reinforced fiberglass backing that provides additional strength to the disc, reducing the risk of breaks or slippages. They also feature a self-sharpening design, which keeps the abrasive flaps sharp throughout its use, minimizing the risk of operator fatigue or discomfort.

There are different types of flap discs available in the market, including type 27 and type 29 flap discs. While both discs are used for similar purposes, the main difference between them lies in their shape and their application. Type 27 flap discs have a flat surface and are ideal for working on flat or curved surfaces, while type 29 flap discs have a tapered profile and are best suited for reaching tight spaces and corners.

In summary, the type 27 flap disc is an important abrasive tool that is highly versatile and efficient. Its ability to contour to the shape of the workpiece, coupled with its ability to perform a wide range of tasks, makes it an indispensable tool in various industries. Furthermore, its safety features, such as its reinforced fiberglass backing and self-sharpening design, ensure that operators can work safely and efficiently with minimal risk of accidents.
