Understanding Diamond Blades

a. Diamond Crystals (Cut)

The diamond used is manufactured or synthetic as opposed to natural. Manufactured diamond is preferred over natural diamond because key characteristics like crystal shape, size, and strength can be closely controlled through the manufacturing process. The ability to control the key characteristics of the synthetic diamond allow for accurate prediction of cutting speed and blade life as well as consistent repeatability. Some other important factors to consider about diamond are the:

• amount of diamond in the segment

• quality of the diamond in the segment

• size of the diamond in the segment

Amount of Diamond:

The amount of diamond in the segment is variable and requires more horsepower as the content of diamond is increased in the segment. Simply put it means that as more diamond is added to the segment more horsepower is needed to make the blade cut. In practical terms this means that blades for high horsepower saws will have more diamond in the segment.

Quality of the Diamond:

The quality of the diamond determines the ability of the individual diamond to resist heat and maintain a sharp point. Better diamonds can hold a point longer at higher temperatures.

Size of the Diamond:

Finally the last thing to consider is the size of the diamond. The individual’s diamond sizes are specified in mesh ranges like 25-35 or 50-60. The higher the numbers the finer the individual particles. In practical application finer diamond is used for critically-hard material like Chert or Quartz while the larger more coarse diamond is used for soft materials like asphalt and soft red clay bricks.

b. Bonding System (Wears)

The bond is a mixture of metal powders used in various combinations to achieve specific wear rates. A correctly-formulated bond holds the diamond in place, just long enough to get maximum use from the diamond points before releasing the stone and exposing the next layer of diamond.

The wear rate for the segment can be simplified to the ability of a metal to resist wear from abrasion. Metals with low abrasion resistance like bronze are considered soft. The soft bonds are mostly made up of soft metals like Bronze and are common when cutting very hard less abrasive material like porcelain. The hard bonds are mostly made up of hard metals like Tungsten Carbide and are common when cutting very soft abrasive materials like asphalt or freshly poured concrete.

The best way to remember bond-to-material application is “opposites attract” - hard bonds for soft abrasive materials while soft bonds are used for hard less abrasive materials. In some extreme cases, it is possible to simply judge the hardness of the blade by noticing the color of the segment. Because soft blades contain a majority of Bronze, the soft blades for extremely hard materials will have a yellow tint to the segment.

How do diamond blades work and what do they cut?

What is a diamond blade?

A diamond blade is composed of a core or body of high precision steel with a mix of metal powder, diamond segments, and a resin bond that keeps it all together. The sizes and thus the hardness of the diamonds is designed with different concentrations, depending on the kind of blade, or in other words, depending on the material that it will cut. As diamond blades professional manufacturers, at SIMA we finish the product by putting it through a specific thermic process that makes it highly resistant and durable.

What is a diamond blade used for?

Diamond blades are an investment. They are not the cheapest option in the market, but their great resistance, accuracy while cutting, and durability make them worthy. Diamonds are the hardest mineral, meaning that they will cut and grind any other material without tearing down.

So, what can a diamond blade cut? Here are some examples:

Concrete and reinforced concrete
Granite, slate and other natural stones
Bricks
Marbles
Glass
Tiles and pavers made of any of the previous materials

As you can see, diamond blades can cut through tough materials like stone. But you should also make sure that you are using the proper tools and machines like a tile saw or a masonry saw with the proper blade diameter.

How do diamond blades work?

As previously mentioned, in order to manufacture a professional-quality diamond saw blade, our experts at SIMA add several particles of different metal powder, such as iron, zinc, cobalt, and tungsten to a core of high-precision steel, and then we finish the product with a professional resin that makes the bond.

But keep in mind that even if it is a blade, it does not actually cut but grind. As explained above, diamond particles scratch every material until it goes all the way through it, meaning that it does not need sharp teeth that could be dangerous for the user but still work perfectly with hard materials.

Now you know what diamond blades are used for, and as you can see, diamond tip circular saw blades are part of essential equipment for DIYers and professionals in the construction industry.

Can you cut tile with a circular saw?

Affirmative, you can cut tile with a circular saw. But, how? Easy: You just need the proper blade, and the process of cutting tile is quite easy, but you need a high-quality diamond blade specially designed for tiles. You can check with our staff to get the proper one or find the information on the label.

A bench-mounted tile circular saw or a masonry saw would be perfect for cutting tile, but a circular saw can also do it. It is key that you respect the standard safety rules to proceed, then place the tile on the circular saw bench so that the blade follows your cutting mark and turn the saw on. While you are cutting, the blade should be covered by a water flow; if it is not, switch the machine off and find out what the problem is. Remember that cutting tile does not require applying too much pressure to the blade. You only need to control the blade through the cut, while the saw sets the guidelines.

The first thing you need to get is a circular saw tile blade, which is the same type of diamond blade that you would use on masonry saws and wet tile saws. It is key that you choose the right diameter of the blade for your saw, so, again, check the information on the label or ask for our help, our experts will be happy to help you.

The second factor you need to consider is that circular saws do not usually count with a water cooling system, making the process a bit tricky. If it is impossible for you to wet cut, dry cutting is an option, but it is absolutely necessary that you get a blade designed for dry cutting. And remember that your workplace shouldn’t be indoors or at least it should be well-ventilated. Always wear your protection gear such as a respirator mask and glasses to protect yourself from the dust cloud that dry cutting usually creates.
