When shopping in the saw blades market, it is common to find the circular saw blades and as is known to all, it is mainly used for cutting some nonferrous metals, soft tubes and pipes and carbon steel with low hardness. At the same time, there are super hard circular saw blades which are used for cutting some hard materials such as stainless steel, heat-resisting iron and so on. OK, in the following article, I will mainly talk about some basic knowledge about such super hard circular saw blades.

At first, let me tell you the different between common circular saw blades and super hard circular saw blades.

During the saw blade productive process, the quality of super hard circular saw blades is controlled strictly and more attentions are paid on the metallurgy molding and the saw blade design, as a result, such circular saw blades can be used to cut hard metal materials quickly, along with good performance of cutting.

The number of saw teeth is different, and its matrix is hardening steel, what’s more, as for the tool bit of saw blade, it is specially made from tungsten carbide and titanium carbide.

With more reasonable and scientific arrangement of saw blade tool bit, it has longer working life and when cutting, it is more stable. In other words, top cutting quality can be guaranteed.

Pay attention on the saw teeth gradient because saw blades with different gradients would be used for different materials cutting, for example, if the saw teeth gradient is 0 degree, it is the special steel cutting saw blade, while if the saw teeth gradient is 7 degree, it can specially used for cutting some soft materials such as aluminum. If the saw teeth is with special cycloid curve design, it can be used to cut all kinds of rolled steel, stainless steel and aluminum, all the saw teeth have to bear cutting loading collectively, therefore its working life would be more longer and the physical strength at every tool bit can reach up to its maximum value, with more cutting speed, there is almost no any frictional resistance when cutting steels, irons and stainless steel.

Don’t worry about the high cutting temperature, it is the common sense that there would be high cutting temperature during cutting process because of heat conduction, however, when using such super hard circular saw for cutting and touching metal edge, you would be astonished it is just the normal temperature.
