The different number of teeth has the following main effects on the saw blade for cutting wood:

1. Different cutting speeds

2. Different glossiness

3. The angle of the teeth of the saw blade itself is also different

4. The body hardness, flatness, end jump and other requirements of the saw blade are also different

5. There are also some requirements for the speed of the machine and the feeding speed of the wood

6. It also has a lot to do with the precision of the saw blade equipment

For example, the 40-tooth cutting is less labor-saving and the sound will be quieter due to the small friction, but the 60-tooth cutting is smoother. Generally, carpentry uses 40 teeth. If the sound is low, use thicker ones, but thinner ones are of better quality. The more the number of teeth, the smoother the sawing profile, and the sound will be quieter if your machine has good stability.

The number of teeth of the sawtooth, generally speaking, the more the number of teeth, the more cutting edges per unit time, the better the cutting performance, but the more cutting teeth need to use more cemented carbide, the price of the saw blade is high, but the sawtooth is too dense , the chip capacity between the teeth becomes smaller, which is easy to cause the saw blade to heat up; in addition, if there are too many saw teeth, if the feed rate is not matched properly, the cutting amount of each tooth will be very small, which will increase the friction between the cutting edge and the workpiece, and affect the service life of the blade. . Usually the tooth spacing is 15-25mm, and a reasonable number of teeth should be selected according to the material to be sawed.
