Continuous vs. Segmented Diamond Blade: Choosing the Right Tool for the Job

Diamond blades are an essential tool in various industries, including construction, masonry, and fabrication. They are specifically designed for cutting through hard materials such as concrete, stone, tile, and ceramics. When it comes to diamond blades, there are two primary types: continuous rim and segmented. Each type has its own unique characteristics and applications. In this article, we will explore the differences between continuous rim and segmented diamond blades, factors relevant to diamond blades, grit size of diamond, diamond concentration, and more.

Continuous Rim Diamond Blades:

Continuous rim diamond blades, also known as continuous rim blades or wet cutting blades, feature a continuous edge with a smooth, solid perimeter that is fully embedded with diamond particles. The continuous rim design provides a clean and precise cut, making it suitable for delicate materials that require a smooth finish. These blades are primarily used for wet cutting applications, where water is continuously supplied to the cutting surface to keep it cool and lubricated. The water also helps to flush away debris, preventing the blade from overheating.

Segmented Diamond Blades:

Segmented diamond blades, on the other hand, have a rim with segmented or gapped edges. The segments are evenly spaced around the rim and are separated by slots. These slots allow for effective heat dissipation during cutting and prevent the blade from becoming overloaded with material. Segmented blades are typically used for dry cutting applications, although they can also be used for wet cutting in certain situations. The gaps between the segments help to remove debris, ensuring a more efficient cutting process.

Factors Relevant to Diamond Blades:

Several factors are relevant when choosing a diamond blade for a specific application. Here are some important considerations:

  1. Material:Different diamond blades are designed for specific materials. For example, blades for cutting concrete may have a different composition and design than those for cutting ceramic tiles. It is crucial to select a blade that is suitable for the material you are working with to ensure optimal performance and longevity.
  2. Blade Diameter: The diameter of the blade will determine the depth of cut it can achieve. Larger blades are typically used for cutting thick materials, while smaller blades are suitable for shallower cuts or intricate work.
  3. Arbor Size: The arbor size of the blade must match the arbor size of the tool you will be using. Using a blade with the wrong arbor size can result in improper fitment and potential safety hazards.
  4. Speed Rating:Diamond blades have speed ratings that indicate the maximum operating speed they can handle. It is essential to match the blade’s speed rating with the speed of the tool to prevent damage to the blade or accidents during operation.

Grit Size of Diamond:

The grit size of the diamond refers to the size of the diamond particles embedded in the blade’s rim. It plays a crucial role in determining the cutting performance and finish quality. Blades with a larger grit size have larger diamond particles, which are more suitable for aggressive cutting of hard materials. On the other hand, blades with a smaller grit size have finer diamond particles, providing a smoother and more precise cut.

Diamond Concentration:

Diamond concentration refers to the amount of diamond particles present in the blade’s rim. Higher diamond concentration blades have more diamond particles per square inch, resulting in increased cutting efficiency and longer blade life. These blades are ideal for cutting hard materials or for heavy-duty applications. Lower diamond concentration blades are suitable for softer materials or lighter cutting tasks.


The choice between a continuous rim diamond blade and a segmented diamond blade depends on the specific application and material being cut. Continuous rim blades are best for wet cutting delicate materials that require a smooth finish, while segmented blades are suitable for dry cutting and heavy-duty applications. When selecting a diamond blade, factors such as material, blade diameter, arbor size, and speed rating should be carefully considered. Additionally, the grit size of the diamond and the diamond concentration are important factors that influence cutting performance and blade longevity. By understanding these differences and considering the relevant factors, you can choose the right diamond blade for your cutting needs, ensuring efficient and precise results.
