The difference between round blades and sharp blades

Round blades and sharp blades are common cutting tools used for cutting and machining different materials. They have different characteristics in terms of appearance, scope of use, and cutting methods.

There are obvious differences in appearance. The main feature of a round blade is that the blade tip is in a rounded shape, that is, the edge forms a circular arc. The main feature of a pointed blade is that the blade has a sharp shape, that is, the edge of the blade forms a sharp angle. The difference in appearance determines their different applications in cutting and machining processes.

There are differences in the scope of use. Round blades for cutting are mainly used for cutting soft materials such as paper, fabric, and rubber. Its advantage is that it is not easy to damage the material during the cutting process, and the cutting surface is smooth. Sharp blades are mainly used for cutting hard materials such as metal, plastic, and glass. Due to the sharpness of the blade tip, the pointed blade can quickly cut hard materials, but it is easy to cause burrs on the material surface.

There are also differences in cutting methods. The round blade mainly adopts rolling cutting method. That is to say, the arc tip of the blade rolls along the material surface during the cutting process, effectively reducing cutting resistance and achieving high cutting quality. The sharp blade mainly adopts pressure cutting cutting method. That is to say, the tool tip directly applies pressure to the material for cutting, which is faster but prone to burrs.

In addition, round blades and sharp blades also have some similarities. They are all cutting tools that can achieve material cutting and cutting. During use, it is necessary to pay attention to the maintenance and timely replacement of the blade to ensure cutting efficiency and tool life.
