A Practical Guide for Cutting Porcelain, Stone & Ceramics
Cutting tiles cleanly is just as important as laying them. Even the most precise installation can be let down by chipped edges, overheating, or poor blade selection.
With porcelain becoming denser and natural stone more widely used, choosing the right diamond blade is essential for achieving clean cuts, reducing waste, and improving efficiency on site.
In this guide, we break down how diamond blades work, the different types available, and how to choose the right one for the job; including the Tylix range.
What Is a Diamond Blade?
Despite the name, diamond blades don’t cut in the traditional sense. They grind through material using industrial diamonds embedded in the rim or segments. As the blade spins:
- Diamonds wear away the material
- New diamonds are exposed
- Heat is generated through friction
The quality of the blade determines:
- Cutting speed
- Finish quality
- Blade lifespan
- Suitability for specific materials
Key Types of Diamond Blades
Continuous Rim Blades (Best for Clean Cuts)
Continuous rim blades have a smooth, uninterrupted edge.
Best for:
- Porcelain tiles
- Ceramic tiles
- Fine finish work
Benefits:
- Minimal chipping
- Smooth, clean edges
- Ideal for visible cuts
These are typically used with wet cutting machines, although some are suitable for dry use depending on specification.
Segmented Blades (Best for Speed & Tough Materials)
Segmented blades have gaps between segments to improve airflow and cooling.
Best for:
- Concrete
- Brick
- General construction materials
Benefits:
- Fast cutting
- Better heat dissipation
- Longer lifespan in tough conditions
However, they produce rougher cuts and are not ideal for porcelain or decorative finishes.
Turbo Blades (Balanced Performance)
Turbo blades combine features of both continuous and segmented rims.
Best for:
- Granite
- Stone
- Some porcelain applications
Benefits:
- Faster than continuous rim
- Smoother than segmented
- Good all-round performance

How to Choose the Right Blade
Selecting the right blade comes down to three key factors:
-
Material Type
- Porcelain → Continuous rim or ultrathin blades
- Ceramic → Most continuous or turbo blades
- Granite/Stone → Turbo or specialised blades
-
Finish Required
- Visible edges → Ultrathin or continuous rim
- Hidden cuts → Turbo or segmented
-
Cutting Method
- Dry cutting (angle grinder) → Ultrathin blades
- Wet cutting (tile saw) → Larger continuous rim blades
- Heavy-duty cutting → Wet blades for cooling and longevity
Pro Tips for Better Cutting Results
- Always match blade RPM rating with your tool
- Let the blade do the work — don’t force the cut
- Use water where possible to reduce heat and dust
- Ensure steady, controlled movement
- Replace worn blades to maintain finish quality
