The fillet knife is a specially designed tool, mainly used for cutting metal materials. Its unique blade design makes the cutting process smoother, reduces vibration and noise, and improves cutting quality. Such tools are usually made of high-hardness materials, such as tungsten steel or high-speed steel, to maintain the sharpness and durability of the blade.

The fillet knife is characterized by the fillet design of its blade. This design allows the blade to better adapt to the shape and texture of the material during the cutting process, reducing stress concentration and friction, thus extending the service life of the tool. In addition, the blade design of the fillet knife is precise, which can achieve high-precision cutting and reduce errors.

Fillet knives are very versatile. It can be used for cutting various metal materials, such as aluminum, steel, copper and so on. In the fields of metal processing, machining, mold manufacturing, etc., the fillet knife is an indispensable tool. It can help workers quickly and accurately complete the cutting task and improve production efficiency.

In addition, the fillet knife maintains a good blade sharpness during the cutting process, which makes it able to maintain cutting performance after a long time of use. This makes the fillet knife ideal for situations that require frequent use or long working hours.

Overall, the fillet knife is an efficient and accurate metal cutting tool. It is characterized by its unique rounded corner design and high hardness of the material, making it excellent in the cutting of various metal materials. Whether it is in the field of metal processing, machining or mold manufacturing, the fillet knife is one of the indispensable tools.
