HOW WE PRODUCE OUR HIGH QUALITY BLADES

CMT stands for quality, which means we put quality into everything we do. It only makes sense. At CMT we figure that if our router bits are going to be top quality, high-performance and orange, then our saw blades should be too.
And to do that, we simply follow the same guidelines for our blades that we do for our bits: we start with a solid design, use only the best materials and manufacture with skill and care. And of course, make sure they are trademark orange.

Always refer to Safety Recomendations to ensure the safest most correct use of CMT blades

DESIGN

The simplicity of a circular saw blade design is in reality a complexity of technical considerations.

Each blade has to make a certain type of cut, and this requires careful analysis of hook and grind angles, gullet designs, to location of sound dampening slots and the thickness of the blade - just to name a few.

So in order for us to get the best design for our blades - and for you to get the best performance from them - we use the same method that we use to engineer our router bits: we combine the knowledgeable minds and experience of our technical department and the latest computer technology. The result is a superior blade that has some rather special “standard” features:

Anti-vibration Design. The anti-vibration cuts in the blade do exactly what their name implies: they are the anti in anti-vibration. This translates into less chattering during cutting and consequently it lengthens the life of the blade. Anti-vibration also means a flawless cut, so stabilizers and scoring blades are no longer necessary.

Expansion Slots. These little hook-shaped cuts in the blade help to reduce noise while regulating the expansion and contraction of the blade as it generates heat during cutting operations.

MATERIALS

When it comes down to it, saw blades are much like router bits - it’s just two components: steel and carbide.
So in selecting the raw materials, we are every bit as picky with our saw blades as we are with our router bits.
Besides, why mess with a winning formula like superior steel and tungsten carbide?

Steel. It’s the heart of the blade, so CMT uses only the finest steel available: super 42-44 Rockwell hardness steel.
Carbide. The cutting tips of every CMT blade are made from the best grades of micrograin carbide.

MANUFACTURING

CMT saw blades are machined on automated CNC machines, from start to finish.

The advanced technology and precision of these machines ensures uniform quality on every blade while giving us the possibility to carry out more efficient quality controls.

Laser Cutting. The steel plate of the blade is laser cut, NEVER die cut, from superior strength steel.

This way of cutting steel is not only extremely precise but it makes it possible to cut harder strengths of steel and does not stress the plate while cutting, so the resulting blade is flat and true and more resistant to warping.

Grinding & Tensioning. After it has been cut, the blade is polished and tensioned, the evidence of which can be seen in the superior finish and a tension ring that are visible on the blade.

Then the central bore is ground to a smooth finish so that the blade will fit precisely on the saw arbor and will have perfect concentricity during rotation.

The seats for the carbide teeth are also ground, making sure that the carbide tips fit perfectly, providing the right conditions for making a secure braze.

All CMT circular saw blades are made with the finest industrial materials and processes.

Two main categories:

1) CONTRACTOR CIRCULAR SAW BLADES.
Designed for contractors, these are the perfect choice combining smooth performance at affordable prices.

2) ITK PLUS® CIRCULAR SAW BLADES
New thin-kerf saw blades which reduce material waste and demand on the saw, while delivering reliable, industrial-quality performance cut after cut.
