Choosing the best diamond blade for cutting asphalt depends on the material, the cutting machine and the demands of the job. Asphalt is highly abrasive, so using a blade designed for this material helps maintain cutting performance and reduce unnecessary wear.
Whether you’re cutting road surfaces, driveways or fresh concrete, matching the blade to the application is essential.
If you want to understand how different diamond blades work, read our Diamond Blades Guide.
For practical advice on equipment and cutting technique, see our Asphalt Cutting Guide.
Asphalt is softer than concrete but can be highly abrasive. A blade designed for ordinary concrete may wear too quickly when used on asphalt, so choosing the correct blade matters.
When comparing asphalt diamond blades, consider:
Bond hardness: Asphalt blades generally use a softer bond to help expose fresh diamond particles as the blade wears.
Undercut protection: Cutting abrasive materials can wear the steel core near the base of the segments. Suitable undercut protection can help reduce this wear.
Cutting performance: The blade should suit the material, cutting depth and machine being used.
Blade life: The right blade can help reduce unnecessary wear and the cost of replacing discs.
Machine compatibility: Always check the blade diameter, bore and maximum permitted RPM against your cutting machine.
The best choice depends on your working conditions and how frequently you cut asphalt.
Capfix supplies diamond blades for asphalt and other abrasive materials. The following options are worth considering, depending on the work you carry out.
The Legate is a laser-welded diamond blade designed for asphalt, fresh concrete and abrasive materials.
It is available in 12-inch and 14-inch sizes, making it an option for compatible cutting machines used on site.
Choose the correct diameter for your machine and check the manufacturer’s specifications before use.
The Black Arrow is designed for cutting asphalt and abrasive materials.
When comparing it with other blades, consider the type of work you carry out, the cutting conditions and the expected blade life. These factors help determine which blade offers the best value for your particular jobs.

The Vanguard is a Diewe diamond blade designed for asphalt and abrasive materials.
It’s an option to consider for site work where you need a blade suited to abrasive cutting conditions. When comparing it with other asphalt blades, consider the material, cutting requirements and expected blade life.
Always check the blade specifications to ensure it’s suitable for your cutting machine and application.
Although some concrete blades may cut asphalt, they are not necessarily suitable for sustained asphalt cutting.
Concrete and asphalt have different cutting characteristics. A blade designed for concrete may wear inefficiently when used on abrasive asphalt, potentially reducing its useful life and cutting performance.
For regular asphalt work, choose a blade specifically designed for asphalt and abrasive materials.

efore ordering, consider these four points:
1. What are you cutting?
Identify whether you’re cutting asphalt, fresh concrete or another abrasive material. The blade must be suitable for the material.
2. Which machine are you using?
Check the required blade diameter, bore and maximum RPM. Never fit a blade that is incompatible with your machine.
3. How deep is the cut?
Choose a blade diameter that provides sufficient cutting depth for the job and is approved for your equipment.
4. How frequently do you cut?
If asphalt cutting is regular work, blade life and cutting performance deserve as much attention as the initial purchase price.
Choosing the right blade helps you get the job done without unnecessary wear, delays or replacement costs.

If you’re unsure which blade is suitable, tell us what you’re cutting, which machine you’re using and the blade size you need. We’ll help you narrow down the options.
A diamond blade designed specifically for asphalt and abrasive materials is generally the best choice. Asphalt blades commonly use a softer bond to help expose fresh diamonds as the blade wears.
Some concrete blades may cut asphalt, but they may wear too quickly or perform poorly in abrasive conditions. For regular asphalt cutting, use a blade designed for the application.
Undercut protection is designed to reduce wear on the steel core near the base of the diamond segments. It can be particularly useful when cutting abrasive materials such as asphalt.
Choose a blade suited to the material and machine, follow the manufacturer’s cutting instructions and avoid forcing the blade through the material. Consider both purchase price and useful cutting life when comparing options.
