Diamond Blades: The Science Behind The Technology

To ensure you are always choosing the right blade for the job it is important to understand the science behind the diamonds.  In this blog, we will look at the composition of the blade and what to look for when selecting the blade based on the material you intend to cut.

Let’s Look at the Blade


From the picture, you can see that the blade is made up of 4 different components. The Metal core is a steel disc in which everything is bonded too, The Diamonds are the sharp cutting teeth that are responsible for making the actual cut to the stone.

The Matrix is the metal bond which holds the diamonds in place and The Weld brings everything together to attach the matrix with the diamonds to the core.

The cut is essentially achieved thanks to the exposed diamonds on the edge of the blade slicing through the stone.

The Wear and Tear

The clever technology side of these blades lies in the wear and tear. When cutting through the stone the matrix will begin to wear away, this will loosen the old worn out diamonds and expose the fresh new diamonds which are embedded further down in the matrix.

This will allow you to continue to cut until the matrix is completely worn away. To ensure you are getting the best out of your blade it is vital to stock up on your Diamond Sharpening Blocks in your tool kit.

These will help you to keep your blade sharp by helping to erode that matrix faster to expose those fresh diamonds to ensure you are always getting the best cut.

Choosing the Right Blade for the Job

Choosing the right blade for the job will depend on both the hardness of the matrix bond and the hardness of the stone.

A softer stone such as Quartz will wear out the diamond slower than a harder stone. This means they require a blade with a harder matrix bond to ensure the diamonds are used to their full potential before they are eroded away.

Harder and manmade stones, such as DEKTON, will wear out the diamonds much faster. This means they need a softer matrix bond to enable a faster erosion of the matrix.

A harder bond would keep the used diamonds in place for longer, which would give you a blunter, less clean cut. Whereas the softer bond will keep up with your diamond requirements and expose fresh diamonds faster, ensuring you always cut at your best.

Part of the testing process here at Stonegate is to ensure we are providing you with the best bond for the stone you are cutting, whilst also focusing on new technology to develop better blades that will last longer, like our brand new TEMPEST blade.

The TEMPEST, which is exclusive to Stonegate is designed with new arranged diamond technology which gives you’re a better cut but lasts 3 times longer. The arranged diamond technology positions the diamonds in a better formation to ensure that when the matrix wears away, it is always exposing new diamonds.

This allows you to cut not only faster, but also at a consistently high standard. This, along with the longevity of the blade makes is a sound investment for fabricators across the industry, providing the best cut possible but also value.
