CMT Scoring Saw Blades

When it comes down to it, saw blades are much like router bits - it’s two components: steel and carbide. So in selecting the raw materials, CMT are every bit as picky with their saw blades as we are with their 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.
Manufacture
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 an optimum, secure braze.
