How to Select the Right Flap Disc?

When it comes to flap discs, there's a variety of discs available in today's marketplace. Let's start by understanding the various components of a flap disc, so you know how to select the right disc for the right task:

Flap Disc Type:

Do you want a aggressive stock removal, or a smooth finish? Choosing the right disc shape is the most important thing, and the shape will help you effectively achieve your results. Flap discs are available in two shapes: T27&T29.

T27 flap discs are ideal choice when you need to grind workpiece with flat surface. Flat flap discs are best for blending and superior finishing. They are mostly used on flat surface. The flaps of a flap disc are adhered to a backing plate which provides stability during operation.

T29 flap discs are your best friends when you need to remove a lot of material in a small amount of time. They can be used for edge-working as well as on contoured applications. The flaps are angled. As a result, these discs offer a greater surface area for stock removal on horizontal surfaces.

Backing plate:

The backing plate material is also an important factor to consider when choosing flap discs for your application. Fiberglass, plastic and metal (iron) are the most popular backing plate materials:

Fiberglass: Being strong, durable, lightweight and safe, fiberglass is the most popular material choice. Fiberglass creates a strong bond with adhesives and does not contaminate the working surface.

Plastic: Another popular backing material is plastic, and nylon is the most commonly used plastic. These backings can be trimmed which allow longer usage of flaps, specifically during blending and finishing. These days, plastic is becoming an increasingly attractive choice due to its conform-ability and costs.

Metal: Metal backing plates are safe choice, and they’re great when you need extra strength and firm support. Metals don’t get consumed during use, but metal plates can be easily recycled when a flap disc is past its useful life.

Flap discs can be used for a variety of applications, whether it's metal or wood, concrete grinding or finishing, stone smoothing or finishing, paint or rust removal, and more. In order to get the maximum benefits out of flap discs, it's important to choose the right abrasive material for your different job needs. Let's look at the most commonly used abrasive cloth types:

Aluminum Oxide:

Aluminum Oxide is the low-cost option. It is economic but has good performance. Today, it is recommended for jobs where the product needs to be rough finish.

Zirconia Alumina:

This is a blend of Zirconia and Aluminum Oxide grain, and it's great for carbon and mild steel application. Zirconia Alumina has aggressive stock removal, and it provides a great cut rate for the cost.

Ceramic: 

This material is great for stainless steel or alloy metals application. Ceramic produces a constant supply of sharp cutting surfaces which means it has excellent self-sharpening. As a result, it enables faster cutting while allowing the entire grain to be used. As the entire grain is getting used up in the cutting process, these discs offer higher durability.
