As you know, there are too many parameters when selecting right saw blade, for example, the types of cemented carbide, the materials for matrix, saw teeth shape, saw teeth amount and saw teeth angle. Believe it or not, among all these technical parameters, saw teeth angle is the most complicated and also the most professional parameter. If you choose saw blade with right angle, the final cutting effect would be more better. When consider saw blade angle, you have to pay attention on these three main parameters including rake angle, clearance angle and wedge angle.

Rake angle is the main factor for cutting strength when cutting wooden materials, generally speaking, the larger rake angle, the saw teeth would be more sharper and its cutting effect would be more better, it is convenient to cutting and lots of physical strength would be saved when feeding materials. For example, if the cutting material is too much soft, it is better to choose saw blade with large rake angle, the reverse is also true.

Can you under the meaning of saw teeth angle? In fact, it is the saw teeth location when cutting and the saw teeth angle will affect the final cutting effect. As for the front rake angle, larger rake angle, the more convenient cutting and it should be between 10 degree and 15 degree. As for the clearance angle, it is the intersection angle between saw teeth and the processed surface and its role is to prevent the drastic friction between them.

In addition to saw teeth angle introduced at here, I also want to discuss the saw teeth shapes such as left-right saw teeth, high-low saw teeth and inverted ladder-shaped saw teeth, as is known to all, different saw teeth would be suitable for cutting different materials. For example, if you are likely to cut solid wood, shaving board and Medium Density Fiberboard, it is better to choose left-right saw teeth because of its sharp cutting result, when using it for cutting, the cutting kerf would be more smooth and wood fiber would be cut decidedly. When cutting and sawing laminated board and board fireproofing, it is recommended to use ladder flat saw teeth because with such saw blade, both edge breakage and saw notch would be reduced effectively. At the same time, its common diameter should be about between 350mm and 450mm while the thickness would be between 4.0mm and 4.8mm.
