TCT Saw Blades – What Are They?

What is a TCT Blade and Why Do I Need One? It can be tempting to make a cut with your circular or mitre saw using whatever blade is already fitted, and you might even get away with it.

However, to ensure the cleanest, safest, most accurate cut each time, using the correct saw blade for the application is vital. Click here to read our guide to mitre saw blades.

In this Toolstop guide, we’ll look at one particular type of saw blade and explain the reasons why you’ll use it.


What is a TCT Blade?

All saw blades are designed for specific types of cut. The kerf – or width of the teeth – will dictate how clean the cut is. However the number of teeth on the blade also plays a part in this; fewer teeth for faster, rougher cuts. Because the material you’re cutting is the biggest factor in deciding the type of saw blade you need. Wood, non-ferrous metals and plastics, require blades designed for these specific materials.

Tungsten Carbide Tips

TCT saw blades are specifically designed for cutting metal tubing, pipes, rails, nickel, zirconium, cobalt and titanium-based metal. All of this is possible thanks to the teeth on the saw blades, and the tungsten carbide tips, or TCT.
It’s this coating of tungsten carbide that gives the saw blades the ability to easily cut through metals, while at the same time ensuring the blades last a long time.
