TCT Blades vs Diamond Blades – What’s the Difference?
If you’re shopping for cutting blades and wondering whether you need TCT or Diamond, you’re not alone. These two blades are built for very different jobs — and using the wrong one can waste time, ruin material, or burn out your tool.
Let’s break down the key differences so you always get the cleanest cut.
🔹 What is a TCT Blade?
TCT stands for Tungsten Carbide Tipped. These circular saw blades are used primarily for cutting wood and wood composites, but can also handle some plastics and aluminium.
✔ Great for:
-
Timber, MDF, plywood
-
Laminate flooring
-
Clean, splinter-free cuts
-
High-speed circular saws, mitre saws, chop saws
🔹 What is a Diamond Blade?
Diamond blades are designed for cutting hard, abrasive materials. Instead of sharp teeth, they use synthetic diamonds bonded to the edge of the blade.
✔ Great for:
-
Porcelain & ceramic tiles
-
Concrete, brick, stone
-
Hard natural materials
-
Angle grinders, tile cutters, floor saws

⚠️ Using the Wrong Blade = Trouble

Using a TCT blade on tiles = chipped edges or broken blade
