TCT circular saw blade now is widely used for cutting, and if you want to buy top quality ones, please not to neglect these parameters such as number of saw teeth and saw teeth angle. Only with reasonable size, it cutting performance would be more better. Firstly, number of saw teeth As is known to all, the cost of production for saw blade with too many saw teeth would be higher because more cemented carbide would be used as raw material for production, therefore its selling price would be higher than other saw blades correspondingly. At the same time, even cutting efficiency can be guaranteed with too many saw teeth, but saw blade’s working life would be one problem which should not be neglected because high cutting temperature at here. Meanwhile, with too many saw teeth, you have to pay attention on feeding amount when cutting, you know, if the feeding amount is not suitable, actual cutting amount is limited and there would be huge friction between cutting edge and cutting raw materials, which also affect its working life. Generally speaking, the gap between saw teeth should be about 15mm to 25mm, of course, you have to choose suitable saw teeth with suitable saw teeth according to practical cutting condition. Secondly, saw teeth angle What is the meaning of saw teeth angle? It is the saw teeth location when cutting and believe it or not, saw teeth angle is closely related to cutting performance. When talking about saw teeth angle, please not to neglect these three angle including front rake angle, relief angle and wedge angle. The front rake angle is the saw teeth pitching-in angle and as usual, the larger front rake angle, the easier cutting performance and it should be between 10 degree and 15 degree. As for the relief angle, it is the angle formed between saw teeth and finished cutting material surface, its role is to avoid friction between saw teeth and cutting material, the larger relief angle, the smaller force of friction and the bright and clean on cutting material surface. The relief angle of TCT circular saw blade would be about 15 degree. Finally, as for wedge angle, it is the derivant of front rake angle and relief angle, in general, wedge angle should not be too small and it plays the role of keeping saw teeth strength, heat dissipation and durable function. The total angle of these three angles should be 90 degree.
