How to differentiate abrasive discs | Stayer

Abrasive discs cut or grind due to the abrasive grains that compose them. This is due to the fact that the binder (natural or synthetic), binds the abrasive grains with different strength to each other so that depending on the purpose of the disc, it has more or less hardness, speed or depth of cut; or roughing capacity.

Therefore, depending on the application you are looking for, there are different types.

Either by the tool that you are going to use (grinder, cut-off saw, pavement cutter, gasoline cutter or stationary machine); the material you want to cut (stainless steel, iron, stone); or the utility that you are going to give it (cut or grind); they will have some characteristics or others.

What are the differences between a cutting, grinding or flap abrasive disc?

The main difference between grinding, flap and cutting discs is that the first two are used to smooth surfaces, remove weld seams and grind edges; and the third to cut.

The grinding discs have a larger and thicker abrasive grain; and the depressed center to favor its resistant to the torsion, has less vibrations and a homogeneous wear.

While flap discs, are formed by several abrasive fabrics depending on the application, and their center is usually depressed when it is going to be used for roughing, although they also exist with a flat center.

However, the cutting discs have a smaller grain size, and a less concave or even flat center.

Finally, it is important to mention that, it is necessary that the grinding and flap discs must be placed at an angle of 20-30 ° with respect to the material, and the cutting discs at 90 °. In this way the cut will be safer and with a perfect finish.

What does the labeling of the abrasive discs mean?

As we mentioned at the beginning of the article, there are abrasive cutting discs (Extrathin or Standard), grinding discs and flap discs. So that there is no confusion to differentiate them, they have a label where the particularities of each are indicated.

Can you distinguish each of the indicated parts? We will explain you one by one.

If flap and grinding discs have similar functions, which one should you choose?

As you have seen, flap and grinding discs have similar functions, but what makes them different? The composition that each one has is different and, therefore, the finish is not the same.

Grinding discs are ideal when you don’t need a fine and precise finish, and flap discs if you want a much more perfect finish.

Today, the trend in the market is for flap discs to replace conventional grinding discs. Until then, the ideal is to use grinding discs for hard grinding, and flap discs for finishing operations.

 If you’ve ever worked with metal or masonry materials, you’ve probably come across cutting and grinding discs. These two tools are commonly used in the construction and manufacturing industries, but do you know the real difference between them? In this blog post, we’ll discuss the differences in thickness and purpose between cutting and grinding wheels to help you understand which tool is best for your specific project.

 First, let’s talk thickness. When it comes to cutting and grinding discs, thickness plays a vital role. For example, let’s look at a 100mm disc. Grinding discs are usually thicker than cutting discs. Regular grinding discs are over 6mm thick, providing stability and durability during grinding. Cut sheets, on the other hand, are much thinner, with an average thickness of about 1.2 mm. This thinness allows for precise, clean cuts that minimize material waste.

 Now that we understand the difference in thickness, it’s worth understanding the different uses for these discs. Grinding discs are mainly used for polishing and smoothing surfaces. They have abrasive properties that remove excess material from the workpiece, resulting in a smooth, uniform surface. This makes the grinding disc ideal for tasks such as removing welds, shaping metalwork, and even sharpening tools. With their thicker profiles, they can withstand the forces and heat generated during long grinding sessions.

 Cut-off wheels, on the other hand, are specially designed for cutting various materials such as metal, concrete or tiles. Their thinner profile allows for precise cuts, allowing for intricate and detailed work. Cut-off wheels are commonly used for applications such as cutting pipe, cutting sheet metal, and even carving grooves in brick. Due to its slim design, the cutting disc is less likely to cause heat damage to the material being cut, reducing the risk of deformation or discoloration.

 When choosing the right disc for your project, it is critical to consider thickness and intended application. Grinding discs are ideal if you need smoothing or polishing tasks. Its thickness provides stability and longevity, ensuring you can get the finish you want. Conversely, if you need to make cuts, a cutting disc will be your best choice. Its low-profile profile guarantees precision for clean, accurate cuts without compromising material integrity.

 To sum up, cutting discs and grinding discs are very different in thickness and use. Grinding discs are thicker and are primarily used for polishing and smoothing surfaces, while cutting discs are thinner and designed for precision cutting applications. Knowing these differences will enable you to choose the most suitable disc for your specific needs, ensuring the success and quality of your projects.
