Diamond Saw Blades
Diamond Blades for Concrete, Asphalt, and Ductile Iron
Diamond blades are essential tools for cutting a variety of materials, including concrete, asphalt, and ductile iron. These blades consist of a steel core, diamond segments, and a bonding agent. The diamond segments are the key component that determines the blade's cutting ability and durability.
In this article, we will explore the differences in metallurgy and diamond concentricity within the diamond segments on the circumference of the diamond saw blades, and how they impact the cutting performance of diamond blades for concrete, asphalt, and ductile iron. We'll answer questions like:
What is diamond blade used for?
Do these blades actually have diamonds?
What are diamond saw blades used for?
What are diamond blades good for cutting?
What blade can cut concrete?
Which diamond saw blades are best for cutting abrasive materials?
We will get answer all those questions and more. First let's learn about the cutting process of diamond saw blades.
What are diamond saw blades used for?
These blades are cutting tools used to cut a variety of materials, including hard concrete, asphalt, stone, tile, and ductile iron in a variety of applications, including construction, road maintenance, and plumbing.
In construction, a concrete saw blade is used for cutting concrete building foundations and roadways. In road maintenance, the blades are used for cutting roads for repairs and maintenance. In plumbing, the saw blades are used for cutting pipes and other materials.
What industries use diamond blades?
These blades are also used in a variety of industries, including mining, manufacturing, and agriculture. In mining, the saw blades are used for cutting rock and minerals. In manufacturing, the circular saw blades are used for cutting a variety of materials, including metal, glass, and ceramics. In agriculture, the blades are used for cutting crops and other materials.
Metallurgy of Diamond Saw Blades
The steel cores of saw blades are made from high-quality steel that is engineered to withstand the high stress and heat generated during the cutting process. The metallurgy of the steel core influences the blade's overall strength, durability, and cutting performance.
For example, high-quality steel with a high carbon content provides greater strength and stiffness compared to steel with a low carbon content. This makes high-carbon steel the preferred choice for diamond blades designed for cutting hard materials such as concrete and ductile iron.
The segments on the circumference of a diamond blade are composed of diamond crystals and a bonding agent. The concentricity refers to the arrangement and alignment of the diamond crystals within the segments. The concentricity of the diamonds has a significant impact on the diamond saw blades' cutting ability, as it directly affects the diamond saw blades' ability to retain its shape and withstand the high stress and heat generated during the cutting process.
The Benefits of Dimaonds Arranged in a Concentric Pattern
Diamonds that are arranged in a concentric pattern within the segment on the diamond saw blades will provide a smoother and more efficient cut compared to diamonds that are randomly arranged. Concentric diamonds are more uniform in size and shape, which reduces the chances of the blade breaking or chipping. This results in a longer lifespan for the blade, as well as improved cutting performance.
Different Regions Have Different Aggregates
In general terms, where you are cutting concrete is important when making your selection on which blade to use on your job site prior to your order. Different regions typically have different aggregates used in the process of mixing concrete.
For example in California, you'll typically find hard materials such as granite, basalt and river rock. Alternatively, in Florida you'll find more soft and abrasive materials like limestone and sandstone.

Diamond Blades for Concrete
Concrete is a hard and dense material that requires a diamond blade with high strength and durability. A diamond blade designed for cutting concrete should have high-quality steel for its core, as well as diamond segments with a high concentricity. The blade's bonding agent should also be engineered to withstand the high heat generated during the cutting process.
The diamond segments on a concrete blade should have a high concentration of diamond crystals, as this will provide a faster and smoother cut even through metal, steel and rebar. The blade's diamond segments should also be positioned in a way that provides maximum exposure to the concrete, metal and other materials being cut. This will help to increase the diamond blades cutting speed and reduce the chances of the diamond blades breaking or chipping.
Asphalt is a softer material than concrete and tends to be one of the more abrasive materials someone might cut with diamond saw blades. Therefore this material requires a diamond blade with a different set of features. A diamond blade designed for cutting this material should have a low concentricity, as this will help to reduce the chances of the diamond saw blades overheating and damaging the material being cut.
The diamond blades' steel core should also be engineered to be more flexible than a concrete blade, as this will help to absorb some of the stress generated during the cutting process. The blades diamond bonding agent should also be engineered to provide a better grip on the asphalt, which will help to prevent the diamond blade from slipping and reducing its cutting efficiency.
Diamond Blades for Ductile Iron
Ductile iron is a tough and durable material that requires diamond saw blades with high strength and durability. Diamond saw blades designed for cutting ductile iron should have high-quality steel for its core, as well as diamond segments with a high concentricity of diamonds. The bonding agent on these diamond saw blades for ductile iron should also be engineered to withstand the high heat generated during the cutting
