Cutting Asphalt: Tools, Blades & How to Do It Properly
Cutting asphalt properly comes down to using the right blade and technique. Whether you’re working on driveways, roads, or patch repairs, using the correct diamond blade for asphalt makes the job quicker, cleaner, and more efficient.
For a full overview of blade types and how they’re used across different materials, see our diamond blades guide.
How do you cut asphalt?
Cutting asphalt starts with choosing a diamond blade designed for abrasive materials. Mark the cutting line clearly, check the required cutting depth and make sure the blade is suitable for the saw or machine you are using.
When cutting, keep the blade moving steadily and avoid forcing it through the asphalt. The correct blade should cut without excessive pressure. Let the blade work at the correct speed to maintain cutting performance and reduce unnecessary wear.
For deeper cuts, make several controlled passes rather than trying to reach the full depth in one go. Always follow the operating instructions for the machine and blade, and take appropriate site safety precautions.
What is the best way to cut asphalt?
Always use a diamond blade specifically designed for abrasive materials. Asphalt is softer than concrete but highly abrasive, so it wears down standard blades quickly if they’re not designed for the job.
Although it is softer and more abrasive than concrete, the overall cutting process is similar. If you’re also working with harder materials, see our guide on cutting concrete for a full breakdown of tools, blades, and techniques.
What blade is used for cutting asphalt?
Asphalt requires a soft-bond diamond blade, which exposes fresh diamonds as the material wears the blade down. On site, using proper diamond blades for asphalt makes a noticeable difference to speed and blade life.

Can a concrete blade cut asphalt?
Technically yes — but it’s not recommended.
Concrete blades wear down incorrectly when you use them to cut asphalt because they are designed for cutting harder materials. As a result, the blades become blunt quickly and cut less efficiently.

- Use the correct blade (soft bond)
- Avoid overheating the blade
- Let the blade do the work
- Check depth before cutting
