How Are Diamond Blades Made?

Diamond saw blades are made by bonding diamond abrasive grains to the steel body of the blade, resulting in a stronger, more resilient blade suitable for cutting even the hardest materials. Before you read on, if you want to know more about what high quality diamond multi tool blades are and what they are used for, you can read our.

Diamond blades consist of four components:

  • steel core (support part)
  • segment (cut part)
  • diamond crystal
  • bonding system
  1. Steel core (support part)

The steel core is usually a flat metal disc that supports the outer segments. The steel core is usually attached to the cut section where the diamond is located, using one of the following methods. The type of diamond blade for angle grinder made will influence the choice of method.

  1. Segment (cut part)

The cutting part of the ridgid metal cutting diamond blade consists of two parts. The first is a diamond crystal and the second is a bonding system that holds it in place and creates the correct wear rate for the intended use.

  1. Diamond crystal

Among diamond saw blades, synthetic or synthetic diamonds are more popular than natural diamonds. This is because there is more control over the size, shape and strength of synthetic diamonds, which means they offer better control during the manufacturing process. This control means more accurate predictions of cutting speed and final diamond blade precision. It also helps to reproduce these qualities consistently.

  1. Bonding system
  • The binder that holds the diamond particles in the diamond concrete saw bladesis formed from a mixture of metal powders. Different metal powders are combined in specific ratios to achieve specific wear rates. The correct wear rate will ensure that the diamond particles remain in place long enough to achieve maximum wear. They will then release them, revealing the next layer of diamond particles below. A soft bond that wears quickly will consist of soft metal powders such as bronze. These are best for cutting materials like ceramics and porcelain, which are very hard but less abrasive. Hard bonds that wear slowly will be composed of hard metals such as tungsten carbide. These are best for cutting materials like asphalt, which is generally soft but hard-wearing. Remember, opposites attract; for harder but less abrasive materials, a softer binder is best. Vice versa, for soft but more abrasive materials, it is better to use a harder binder.

What considerations to be made before using diamond saw blades?

  1. Number of diamonds

The intended use of the blade will determine the number of diamonds used. The more diamonds used in the blade, the more horsepower the blade needs to cut effectively. For example, a blade used to cut materials such as concrete has more diamonds than a blade used to cut ceramics. Since harder materials generally require more tools with more horsepower, more diamonds are needed to get an effective diamond blade.

  1. Quality of diamond

The quality of the diamond used in a diamond blade will determine the heat resistance of the diamond and its ability to remain sharp. High-quality diamonds last longer and stay sharp at higher temperatures.

  1. Diamond size

Diamond size is specified by grid range, such as 25-35 or 50-60. The larger the number in the grid size, the finer the individual diamond particles. While coarse diamond particles are better for cutting asphalt and red bricks, finer diamond particles are better for cutting very hard materials such as quartz.
