Double-Bevel Flat Slitter Knives

Double-Bevel Flat Slitter Knives are precision cutting tools designed for slitting machines, rewinders, pneumatic knife holders, and other slitting systems. Their double-bevel edge geometry provides sharp, stable, and consistent cutting performance for high-speed slitting.
They are suitable for paper, paperboard, plastic films, aluminum foil, laminates, flexible packaging, nonwoven materials, and adhesive materials. A mirror-polished surface finish can help reduce material and adhesive buildup, surface friction, and dust during demanding slitting operations.
As a custom slitter knife manufacturer, WINGCHONG KNIFE can produce double-bevel flat knives in customized diameters, thicknesses, bevel angles, materials, edge geometries, and surface finishes according to your machine configuration and application requirements.
