The paper cutting knife is a major machine knife that is widely used in paper cutters and three-sided paper trimmers, and is an integral part of the cutting process.

The paper cutter has three main materials, standard steel, high speed steel and tungsten carbide inlay. Tungsten carbide is undoubtedly the best material choice, although the cost is high, if used properly, the service life is about three times that of HSS. However, the most popular material for customers is HSS W18Cr4V. This material is much better than some other suppliers' HSS W6Mo5Cr4V2. Therefore, customers must specify the specific material when selecting the paper cutting knife.

In addition, we have an inventory of Polar paper cutting knives made of W18Cr4V. Once the customer decides to test the quality of our knives, we can send samples immediately. And we guarantee that the quality of the bulk order is the same as the sample sent.
