Tungsten Carbide Circular Slitting Knives

Apex Shears offers a wide range of custom-made solid TC Razor Circular Knives for Carton, Paper and Cardboard Industry. Compared to HSS and D2, Tungsten Carbide has many advantages which are suitable for many slitting applications. The most important advantage is very long running life. In many situations, it can be as much as 10 to 20 times as seen in the paper, cardboard or corrugated container industry. The mirror finish provides protection from glue adhering to the knife which in turn protects against knife breakage caused by uneven pressure. The sharper cutting edge produces less dust, making for a cleaner working environment. Although the Tungsten Carbide knife is brittle, the high cobalt content increases overall strength. In addition, the new process HIP, (High Isothermal Pressure) improves knife stability dramatically.
