Cutting 20mm thick porcelain tiles requires precision, the right technique, and, most importantly, a high-performance diamond blade. At Diamond Discs Direct, our Hero Blade Range is designed specifically for hard porcelain, delivering smooth, chip-free cuts every time.
The Best Blade for the Job
For the best results, we recommend using the Hero Turbo Mesh Blade, available in:
✅ 115mm & 125mm – For angle grinders (ideal for smaller cuts and shaping)
✅ 230mm & 250mm – For wet cutting table saws (perfect for long, precise cuts)
✅ 300mm – For Stihl petrol saws (great for on-site cutting of large format tiles)
With an ultra-thin turbo mesh rim, these blades provide fast, smooth, and precise cuts while reducing chipping.
Step-by-Step Guide to Cutting 20mm Porcelain Tiles
1. Choose the Right Blade & Saw
-
Angle Grinder (115mm/125mm): Best for small cuts and shaping.
-
Wet Cutting Table Saw (250mm): Ideal for clean, straight cuts.
-
Stihl Petrol Saw (300mm): Perfect for outdoor and on-site cutting.
2. Mark Your Cut Line
Use a pencil or marker and a straight edge to outline your cut. Applying masking tape along the cut line can help reduce chipping.
3. Cut in Stages
Rather than forcing the blade through in one go:
🔹 Score the surface first to create a guiding groove.
🔹 Make multiple shallow passes for a cleaner cut.
4. Keep the Blade Cool
To prevent overheating and extend blade life:
💦 Use water (if cutting with a wet saw).
⏸️ Take breaks between cuts (if using an angle grinder or petrol saw).
5. Smooth the Edges
After cutting, use a diamond polishing pad or a rubbing stone to refine the edges for a professional finish.
