What is a cutting disc?

A cutting disc is a cutting tool typically made of a thin and sturdy circular steel blade with sharp teeth on its edge. It is designed for cutting operations at high speeds. This type of disc is suitable for cutting heavy objects and can withstand greater impact compared to other cutting tools. The cutting disc generally has a long lifespan due to the use of highly durable metallic materials.

Cutting discs for small tasks:

115mm cutting discs is commonly used for cutting small objects with relatively thin thickness. It can easily cut objects such as metal pipes or moderately thick metal sheets.

Tools for large-scale cutting:

For cutting heavy metal components, stone slabs, etc., 230mm cutting discs is usually required. This type of disc has a diameter of 230mm and enables deeper cuts.

What precautions should be taken when using a cutting disc?

There are several precautions to consider when using a cutting disc. The centrifugal force and friction generated by its high-speed rotation can pose potential dangers. Therefore, it is important to take safety measures such as wearing safety goggles, gloves, or earplugs to avoid accidents and ensure personal safety. Adequate ventilation should be provided during work to prevent metal particles or sawdust from spreading throughout the workspace. It is also essential to prevent the presence of flammable substances to avoid the risk of explosions.


Why is it important to choose the right size?

Cutting discs come in various sizes, and selecting the correct size is crucial as it directly affects work efficiency. Common sizes include 115mm and 230mm, which are suitable for different cutting requirements, ensuring improved cutting effectiveness.

What applications can cutting discs be used for?

Cutting discs are commonly used for cutting metal, stone, and wood. In automotive repair and manufacturing, they are used for cutting metal parts and body repairs. Additionally, certain woodworking workshops also utilize these products. When using cutting discs, it is important to choose high-quality products and follow proper operating procedures. Regularly inspect the discs for any damage or wear and replace them promptly. Avoid using cutting discs for tasks that exceed their specifications and capabilities to prevent safety risks.


In summary, I have introduced the usefulness and advantages of cutting discs, explained the available sizes and their respective applications. The categorization is primarily based on small tasks and large tasks, where different industries require different sizes and specifications of cutting discs according to the materials and metals they need to cut. Safety guidelines must be strictly followed during the cutting process.
