What is the Distinction Between Asphalt and Concrete Blades?

When it comes to construction and renovation projects involving roads, driveways, and other paved surfaces, the choice between asphalt and concrete is crucial. Equally significant is selecting the appropriate blade for cutting and shaping these materials. In this article, we will delve into the key differences between asphalt and concrete blades, considering their bond, design, price, and various applications.


Bond of the Blade:

The bond of a blade refers to its ability to hold the diamond segments together. In the case of asphalt diamond blades, a softer bond is used. Asphalt is a relatively softer material compared to concrete, and a softer bond ensures that the blade cuts through the material more effectively. This bond allows the diamond grits to wear out more rapidly, enabling the blade to maintain its cutting efficiency throughout the project.

On the other hand, concrete diamond blades require a harder bond to withstand the abrasive nature of the material. Concrete contains aggregates such as sand and gravel, making it significantly harder than asphalt. The hard bond of a concrete blade ensures that the diamond segments remain intact and the blade retains its cutting efficiency even under prolonged use.


Design of the Blade:

The design of a blade plays a vital role in determining its cutting performance and efficiency. Asphalt diamond blades typically have a segmented design, with the diamond segments evenly spaced along the rim of the blade. This design allows for better cooling and prevents the blade from overheating during cutting. The gaps between the segments also help in the removal of debris, ensuring smoother and more efficient cuts through the asphalt.

Concrete diamond blades, on the other hand, often have a continuous rim design or a turbo rim design. Continuous rim blades have a solid rim with a smooth edge, which is ideal for making precise cuts in concrete. Turbo rim blades have a serrated rim that provides faster cutting speeds and improved cooling. This design is suitable for general-purpose cutting of concrete, including slabs, walls, and pavers.


Price of the Blade:

The price of a blade is an important consideration when choosing between asphalt and concrete blades. Asphalt diamond blades are generally less expensive compared to concrete blades. This price difference can be attributed to the different materials and designs used in their construction. Asphalt blades typically have fewer diamond segments and a softer bond, which reduces their manufacturing costs.

Concrete diamond blades, on the other hand, are more expensive due to their harder bond and specialized designs. The increased durability and performance of concrete blades justify their higher price point. However, it is important to consider the specific needs of the project to determine whether the additional investment in a concrete blade is necessary or if an asphalt blade will suffice.


Uses of the Blade:

Asphalt Diamond Blades:

Cutting Asphalt: The primary use of an asphalt blade is cutting through asphalt surfaces, such as roads, driveways, and parking lots. They are specifically designed to handle the softer nature of asphalt, ensuring efficient cutting and extended blade life.

Repair and Maintenance: Asphalt blades are also used for repair and maintenance work, such as removing damaged sections of an asphalt surface or creating clean edges for patching.

Concrete Diamond Blades:

Cutting Concrete: Concrete blades are designed to cut through various types of concrete, including slabs, walls, and precast elements. They offer the necessary durability and precision required for concrete cutting applications.

Masonry Work: Concrete blades are also suitable for cutting other masonry materials like bricks, blocks, and stone. They provide accurate and clean cuts, making them essential for construction and renovation projects.


Application of Blade:

Asphalt Diamond Blades:

Road Construction: Asphalt blades are extensively used in road construction projects to cut through asphalt pavements and create smooth edges for seamless integration.

Driveway Installation: During driveway installation, asphalt blades are employed to cut the asphalt material to the desired shape and size.

Parking Lot Maintenance: Asphalt blades are indispensable for maintaining parking lots, allowing for precise cuts to repair potholes or damaged sections.

Concrete Diamond Blades:

Construction Projects: Concrete blades are essential for a wide range of construction projects, including building foundations, walls, and floors. They are used to cut concrete with accuracy and precision.

Demolition: When demolishing concrete structures, concrete blades are employed to make controlled cuts, ensuring the safety and efficiency of the process.

Landscaping: Concrete blades find application in landscaping projects, such as cutting concrete pavers or creating decorative concrete elements like steps or curbs.



Choosing the right blade for asphalt or concrete cutting is vital to ensure efficient and cost-effective results in construction projects. Understanding the differences in bond, design, price, uses, and applications between asphalt and concrete blades is crucial for making an informed decision. By considering the specific requirements of the project, professionals can select the most suitable blade, optimizing performance and achieving desired outcomes in their paving and construction endeavors.
