When people first learn about  “diamond blades” being saw blades, the question you would often hear is that “do they have real diamonds on it?” Most people think that the question may seem funny, especially knowing that saw blades are used in cutting metals and woods and are mainly used in construction, so why would you put a real diamond on it. But then again, why did the industry call them diamond blades?

That is the question we’re going to answer for today.

As mentioned, a diamond blade is a type of saw blade which has diamonds fixed on its edge allowing it to cut hard materials, including the most abrasive ones. From cutting concrete, asphalt, coal balls to wood, semiconductors, and even gemstones, diamond blades have a wide range of use. It also comes in different types and sizes, each designed for specific saw equipment.

Now that you understand its use, you might wonder where the diamonds come into place. Like it was stated earlier, the diamonds are placed or encrusted into the edge of the blade, which makes it possible to cut any abrasive materials. As we all know, diamonds is one of the hardest natural substances known, and there is even a saying that goes, “only a diamond can cut a diamond.” With that being said, its properties allows to almost cut into anything.

So again, we go back to the question, “do diamond blades have real diamonds?”

Well, the answer is no. Diamond blades only have synthetic diamond particles on its diamond segments. These diamond segments, or the cutting edge of the blade, are made from diamond crystals which were heated with powder metal and then pressed into a molding, forming it. The diamond segment is then welded to the steel core to create the diamond blade.

And here’s another interesting fact about diamond blades. These blades don’t actually cut materials, what they actually do is grind to pierce through the material. The exposed diamond crystals on the segments are the ones that do the grinding, and the metal bond is what holds the diamonds in place. As the blade rotates, the diamonds grind the material’s surface into a fine powder, which explains how it can able to cut the most abrasive materials.

After several uses, the diamonds and the metal bond eventually wear out until the cutting section is consumed. By then, the blade will no longer be able to grind. And that is the perfect time for replacements.
