The Truth About Diamond Blades: Do They Really Contain Diamonds?

Diamond blades are indispensable tools in various industries, from construction to gem cutting. They are renowned for their efficiency in cutting through hard materials like concrete, asphalt, and even gemstones. But have you ever wondered if these blades actually contain real diamonds? Moreover, what are segments, and how do they contribute to the blade’s functionality? In this article, we delve into the basics of diamond blades, exploring the composition, structure, and functionality behind these essential cutting tools.

Do Diamond Blade Really Contain Diamonds?

Understanding Diamond Blades:

At first glance, the term “diamond blade” might imply that the blade itself is composed entirely of diamonds. However, this is not the case. While diamonds are indeed a key component, they are not the sole material used. In fact, the diamond content in a typical diamond blade is relatively low compared to the overall composition.

Diamond blades consist of two primary components: the steel core and the segments. The steel core serves as the structural backbone of the blade, providing stability and support during cutting operations. Meanwhile, the segments are the outer edge of the blade where the diamonds are embedded.


Diamonds in Blade Segments:

The segments of a diamond blade are where the magic happens. These are the sections of the blade that come into direct contact with the material being cut. Each segment contains a mixture of diamonds and metal powders, typically bonded together using a metal matrix.

Contrary to popular belief, the diamonds used in diamond blades are not the dazzling gemstones we commonly associate with jewelry. Instead, they are industrial-grade diamonds, which are specifically manufactured for cutting applications. These diamonds are synthetically produced under high-pressure, high-temperature conditions, making them extremely durable and suitable for cutting hard materials.


The Role of Segments:

Segments play a crucial role in the cutting process. As the blade rotates, the segments make contact with the material, initiating the cutting action. The diamonds embedded within the segments act as abrasive particles, grinding away the material with each rotation of the blade.

However, the effectiveness of a diamond blade depends not only on the quality of the diamonds but also on the design and composition of the segments. Various factors, such as the size and concentration of diamonds, the type of metal matrix, and the segment’s bond strength, can influence the blade’s cutting performance.


Types of Segments:

Diamond blade segments come in a variety of shapes and sizes, each designed for specific cutting applications. Some common segment configurations include:

  1. Segmented Rim:Segmented rim blades feature large, continuous segments with gaps between them. These blades are ideal for general-purpose cutting of materials like concrete, brick, and masonry.
  2. Turbo Rim: Turbo rim bladeshave a serrated edge with narrow ridges, allowing for faster cutting speeds and improved cooling. They are commonly used for cutting through hard materials such as granite, marble, and ceramic tiles.
  3. Continuous Rim: Continuous rim bladeshave a smooth, continuous edge without any breaks or segments. This design provides a clean and precise cut, making them suitable for delicate materials like glass and porcelain.
  4. Segmented Turbo: Segmented turbo bladescombine the features of segmented and turbo rims, featuring both large segments and serrated edges. These blades offer a balance of speed and precision, making them versatile for various cutting tasks.



In conclusion, while diamond blades do contain diamonds, they are not entirely made of these precious gemstones. Instead, diamonds are strategically embedded within the segments of the blade, where they act as abrasives for cutting hard materials. The design and composition of these segments play a critical role in the blade’s performance, with various configurations available to suit different cutting applications. By understanding the basics of diamond blades and segments, professionals can make informed decisions when selecting the right tool for their cutting needs, ensuring efficiency, precision, and safety in their operations.
