Most rotary slitter blades feature a beveled edge for optimal cutting power. A beveled edge allows a blade to slit material instead of creating standard cuts. When a metal slitting knife has the primary purpose of making punctures, it will have teeth. These teeth create smaller slits in progression, such as the ones found on tear-off paper products.


The best shear slitting blades are widely used in flexible materials like paper mills, foil & film, paper products, printing, adhesive tape, plastic & rubber, nonwoven & textile, compounds, etc. We can produce several hundred customized slitting blades, including toothed, sawed, corrugated, dished, arrow, multi-grooved, compounded, etc.
