TCT and diamond saw blades can both have circular steel bodies, but their cutting edges and typical applications are different. The first question is what material you need to cut—not which blade looks more robust.
What is a TCT saw blade?
TCT means tungsten carbide tipped. Individual carbide teeth are attached around the blade body. Application-specific TCT saw blades are widely used for wood, wood-based panels, aluminum and other suitable materials. The tooth design must match the intended material.
What is a diamond saw blade?
A diamond blade carries industrial diamond abrasive in its rim or segments. Diamond saw blades are widely used for concrete, masonry, stone, granite, ceramic and porcelain. Check the specific blade's stated material and wet/dry operating conditions.
The main difference: teeth versus abrasive
TCT blades cut primarily with shaped carbide teeth. Diamond blades cut and grind with exposed diamond abrasive held in a bond. This is why the two product families are optimized for different materials.
Which should you choose?
For woodworking, a suitable TCT blade is normally the relevant product family. For concrete, granite or porcelain, a diamond blade is generally the appropriate category. Specialized multi-material products exist, so always check the exact product specification rather than choosing by appearance. For blade dimensions, see our diamond blade size guide.

FAQ
Can a TCT blade cut concrete?
Standard woodworking TCT blades are not designed for concrete. Use a product intended for the target material.
Can a diamond blade cut wood?
Diamond blades are generally selected for hard mineral materials, although specialized multi-material products exist. Follow the manufacturer's stated application.
Which blade lasts longer?
There is no useful universal comparison because the blades serve different applications. Compare products under their intended working conditions.
