Remember the article we posted last September, it was a post about one of the most common questions in our industry, “do diamond blades have real diamonds?” Well, we decided to search Quora.com, and we saw another question somehow similar to this.

The question was “why are diamonds fixed in diamond saw blades?” With that question somehow being similar to the first article we did, we decided that it would be perfect for the topic of today’s post.

First, let’s break it down. Why do these blades use diamonds in the first place?

Well, basically, diamond is regarded as the second hardest material in the world, only after a wurtzite boron nitride was discovered in 2009. But when it comes to the Moh’s scale, diamond is still the known hardest natural material found o Earth. It is extremely hard that only another diamond can scratch it, which makes it the perfect gemstone to use in engagement and wedding rings, which are usually worn every day.

But do diamond blades used the same diamonds in wedding rings and jewelry? The answer is no. Diamond saw blades only used synthetic diamonds or also referred to as industrial-grade diamonds. And although they are called synthetic and are actually lab-made, these diamonds possessed the same toughness and hardness as natural diamonds do. Due to that fact, they are used to polish, cut, and grind away any other material including real diamonds. You’ll find these synthetic diamonds used in drilled-bits and of course, saw blades.

Another thing is the diamonds in your saw blades actually don’t cut materials. They actually grind the materials into thin powder so the blade can pierce through it. These allow the diamond saw blades to be able to cut through abrasive materials such as concrete and asphalt.

But how are these synthetic diamonds placed in saw blades? Well, after the synthetic diamonds are divided into several small pieces, they are heated with metal powder. The diamond and metal mixture is then poured into a mold, forming the diamond segment or the diamond edge of the blade. After the diamond blade is completely solid, they are then welded by the manufacturer into a steel core to create the saw blade.

Each of these diamond saw blades is then labeled with their specific requirements to know which saw they are compatible with. This is very important especially when customers are buying a replacement blade for their saw since a wrong blade can cause problems to its users, and worse comes to worst, it can lead to accidents.

An incompatible blade can damage your saw, wobble when the equipment is rotating, or even cause a kickback while using it. That’s why you should know which diamond blade is compatible with your saw equipment and its RPM.

If you’re buying from an online store, don’t be afraid to call the website’s contact number and ask for assistance to make sure that you’re purchasing the right diamond blade.
