Buying Guide: Key Considerations For 20mm Porcelain Slabs
- Blade Type and Compatibility: Choose a blade specifically designed for porcelain, with a thin kerf to minimise waste and heat. Confirm bore size matches your power tools (22.23 mm is common in UK tools).
- Dry vs Wet Cutting: Many blades perform best with water cooling to reduce heat, prevent edge chipping and extend blade life. If your setup lacks a water feed, ensure the blade is rated for dry cutting.
- Blade Diameter: Larger diameters (e.g., 300–350 mm) are suitable for table saws and wet saws, while smaller 115–125 mm blades suit handheld angle grinders for quicker, on‑site cuts.
- Continuous Rim vs Segmented Rim: Continuous rims tend to produce smoother edges with porcelain; segmented rims can cut faster but may require more finishing to remove chips.
- Material Coverage: For 20 mm porcelain slabs, look for blades engineered for porcelain and ceramic materials, with features such as turbo/mesh rims or diamond matrix optimized for hard tiles.
- Durability and Longevity: Long‑lasting rims and sintered designs resist wear, maintaining edge quality over many cuts, which is important for large tile projects.
- Edge Quality and Finish: A blade with minimal chipping delivers a professional edge suitable for grout lines and flush installations, reducing extra work on site.
- Tool Compatibility: Check your grinder or tile saw’s maximum RPM and ensure the blade’s RPM rating aligns with your machine for safe operation.
- Pricing and Availability: In the UK, availability of 20 mm porcelain blades varies by brand; consider twin packs or multi‑blade sets for value on larger projects.
- Safety: Always use appropriate PPE, including eye protection, gloves and a dust mask; secure slabs properly to prevent kickback during cutting.
