A Beginner’s Guide to Diamond Saw Blades.

Diamond saw blades are tools that cut through rigid materials such as stone, ceramic, concrete, asphalt, and more. While it is called a diamond cut, the blades work by grinding through materials. The blade has synthetic diamond particles mixed with different powdered metals in precise amounts to form a strong bond.

Selecting the right diamond sawing blade can be a challenging endeavour. You need to identify the blade that will suit the machine, what you plan to cut, and how deep you want to cut through the material. There are several components to consider when you choose a cutting blade. 

For example, if you need to make a curve, your blade choice depends on factors like blades with narrow widths make straighter cuts in thicker materials. Considering these factors, one must determine the appropriate width of the blade. 

Additionally, the number of teeth per inch in the blade will also have an impact on the cut. As a general rule, the more teeth per inch, the finer the cut will be, and the fewer teeth per inch, the rougher the cut will be.

Types & Uses Of Diamond Cutting Blades

Knowing the purpose of a diamond blade and its suitability is essential before you use it. These blades are made up of diamond grit and metal powders. They are available in various depths and ingredients depending on the intended use. 

Let us look at the different types of diamond cutting blades:

  • Segmented Rim

It is the most common diamond blade. It has around 10 to 14 individual segments separated by gullets of various depths. It requires water to cool down and is considered best for concrete, masonry, and brick.

  • Turbo Rim

Like segmented rim, turbo rim has similar segments but the anatomy of it is different. The Turbo blade is divided into various sections and has relief holes to ensure the heat is transferred quickly and more efficiently. The advantage of a turbo rim blade is its ability to handle high temperatures uniquely. It is suitable for both wet and dry conditions.

  • Continuous Rim

A continuous Rim blade is used for wet cuts. It is flat and needs to be operated with water passing over it. However, it does not come with inbuilt heat distribution of the fan that can help air to go through the blade.

Dos and Don’ts of Diamond Blades


  • Read the safety instructions thoroughly provided by the diamond sawing company.
  • Store blades in dry environments. Please ensure the temperature variations.
  • Please confirm the product is perfect for your task.
  • Handle and transport the blade with care.
  • Switch off the power to the machine before you fit the diamond blade.
  • Inspect all products before mounting.
  • Have regular maintenance for the blade.
  • Please ensure you are using clean, undistorted, and free mounting devices.
  • Use a well-designed and adjusted guard.
  • The workpiece should remain secure throughout the procedure.
  • Wear safety equipment at all times.


  • Allow untrained workers to use abrasives.
  • Use the damaged product.
  • Avoid using a product that you cannot identify.
  • Use machines with defective parts.
  • Exceed the maximum operating speed mentioned on the product; otherwise, it will be overheated.
  • Grind the part of the product that is not meant for chewing.
  • Use the blade with missing segments.
  • Use abrasive near flammable products.
  • Please ensure the workpiece is not in contact with abrasive when you start the machine.
  • Let the abrasive stop naturally; do not apply pressure to the surface to stop it.

Limitations of Diamond Blade

  • It is a time-consuming process.
  • It has low thermal stability, chemical reactivity with a group of iron elements, and carbonisation at 700 to 800 celsius, which is usually not favourable for steel production. 
  • It is not advisable to use diamond cutting tools made out of high melting temperature metals. 

Quality of a Saw Blade

The Bottom Timber of the Blade

The quality of a diamond saw blade will decide the quality of your cut. Consider the cut and the bottom of the timber when you buy the saw blade because the edge raises through the material and drives out of the cut through the bottom.

The Top Timber of the Blade

The blade will not be useful if the top of the timber is damaged or worn out. It is effortless to spot the crack in the blade. 


For more delicate cuts, speccing will not serve the purpose. You can go for 90 teeth blades, but there is nothing wrong with 60 teeth for ultra-smooth cutting. Search for laser-cut edges with large carbide tips to have more features; choosing them will extend the blade’s lifespan.
