As time advances, science and technology are also developing. The common use of spiral cutter heads is a very good example of the advancement of technology. In the woodworking machinery industry, the spiral cutter head(or helical cutter head) is gradually taking the place of the traditional flat cutter head. Nowadays, more factory is changing the spiral cutter head for woodworking. For example, in Europe and the United States, the spiral cutter head has become the most popular thing in woodworking machinery. Due to this, there’s no difficulty for us to predict that the spiral cutter head will be found almost everywhere you can see the wood processing in the near future, not just in the factory, but also in the personal wood processing workshop. As for the traditional flat cutter head, it will be taken off the market gradually.

But why do more and more people or factories choose to use helical cutter heads for wood cutting or processing? The simple explanation is that the traditional flat head mainly depends on the sharpness of the flat knife while the spiral cutter head is more scientific to evenly distribute the planing point to each blade and at the same time fine-tune the blade and the processing surface angle. By doing this, the spiral cutter head can be easily adjusted to adapt to different materials processing.

What’s more, the tungsten carbide spiral cutter head for woodworking has a smaller cutting contact area than flat cutter heads, which means it has smaller cutting resistance and friction. Because of the small resistance and friction, the tungsten carbide spiral cutter head will produce less heat and noise than flat knives. What’s more, the knives loaded on the tungsten carbide spiral cutter head have a longer service life.

However, as the spiral cutter head is becoming the dark horse in the woodworking machinery market, many of us still know little about the spiral cutter head.

Like how to choose the right type of spiral cutter head for woodworking. In this article, we will solve this problem.

But first, we need to know the classification of spiral cutter heads.

Generally speaking, there are three types of tungsten carbide spiral cutter heads for woodworking. They are the heavy-duty spiral cutter head, the light-duty spiral cutter head, and the spiral cutter head with a shear angle. Here comes another question, what are they used for? Or we could also say, what are their differences and their similarities?

The difference between the light-duty spiral cutter head and the heavy-duty spiral cutter head. The main difference between these two types of cutter heads is their cutting force. Because of the different cutting forces, the shaft of the heavy-duty spiral cutter head can sustain a higher cutting force than the shaft of the light-duty spiral cutter head. But both of them can be used on almost the same material and can be loaded on the four-side molder. As for the spiral cutter head with shear angle, it is mainly used for solid wood, veneer, and plastic processing. And of course, they have different shapes.

Although these three types of tungsten carbide spiral cutter heads for woodworking do not have so many differences, you still need to notice that different types of spiral cutter heads should be loaded with different types of tungsten carbide blades. Otherwise, the tool may be damaged and even may cause injuries. So be careful when you use these tools.
