When buying TCT circular saw blade, please not to ignore the saw teeth angle parameter, in fact, lots of people would be confused with such parameter because it is more complicated and more professional, but if you want to choose top quality saw blade, you should be careful about it because there is close relationship between saw teeth angle and cutting quality.

When talking about saw teeth angle, there are three angles which should be paid attention by you, including the front rake angle, relief angle and wedge angle.

With such rake angle, the consumption strength when cutting wooden material would be affected, as usual, the larger front rake angle saw teeth, the better cutting performance, meanwhile, it is more convenient to finish cutting task because it is easy to push cutting materials. Generally speaking, if cutting material is soft, front rake angle should be larger, the reverse is also true. According to saw blade expert, such front rake angle should be about 10 Celsius degree and 15 Celsius degree.

Relief angle is the one between saw teeth and finished cutting part, with such angle, the force of friction between saw teeth and cutting material surface should be avoided.
