When selecting a wet saw blade for porcelain tile, it’s critical to choose a blade designed for precision, durability, and minimal chipping. Porcelain is notoriously hard and brittle, requiring specialized diamond blades with features that reduce heat buildup and ensure clean cuts. Below is a detailed guide based on search results:
Key Features to Look For
- Continuous Rim Design:
Blades with a continuous rim (smooth edge) minimize chipping and provide clean cuts. These are ideal for porcelain and ceramic tiles . - Diamond-Embedded Segments:
High-quality diamond grit ensures longevity and efficient cutting. Look for blades with a “turbo mesh” or “R-Mesh” design to reduce friction and heat . - Wet-Cutting Compatibility:
Wet blades use water to cool the blade, preventing overheating and prolonging its lifespan. Avoid using dry blades for porcelain, as they can overheat and degrade quickly . - Thin Kerf and Reinforced Core:
Thinner blades (e.g., 1.1–1.2mm) cut faster and produce less dust, while reinforced cores reduce vibration and bending during cuts . - Bond Type:
Medium or soft bonds are recommended for hard materials like porcelain, as they expose fresh diamonds gradually for consistent performance .
