Hole Locking Flat Knives are precision slitting knives designed with mounting holes, threaded holes, or locking configurations for secure installation on knife holders and slitting systems. They are suitable for pneumatic knife holders, shear slitting systems, slitting machines, rewinders, and converting equipment.
Different hole configurations, including round holes, slotted holes, and keyway holes, are available to meet different mounting and machine requirements. These knives provide stable cutting performance for high-speed slitting of paper, paperboard, plastic films, aluminum foil, laminates, flexible packaging, and nonwoven materials.
A mirror-polished finish is available to reduce surface roughness and material or adhesive buildup during slitting. It is particularly suitable for adhesive materials, laminates, woven fabrics, and nonwoven materials, helping maintain a cleaner cutting edge and reduce dust.
As a custom slitter knife manufacturer, WINGCHONG KNIFE can manufacture hole locking flat knives with customized dimensions, hole configurations, keyways, edge geometries, materials, surface finishes, and tolerances according to your machine and mounting requirements.

Abrasive Cutting Knives are industrial cutting tools specifically designed for cutting abrasive rolls such as sandpaper and abrasive cloth.
Dished knives are circular cutting tools used for shear-type slitting. Unlike completely flat “flat knives,” their blades feature a concave geometric shape (resembling a plate or dish), a design that enables them to generate specific lateral cutting forces during rotational shearing.
Adhesive materials: Self-adhesive labels, adhesive tape, various composite films (die-cutting can create a temporary seal along the cut edges).
Elastic/soft materials: Rubber, non-woven fabric (NWF), textiles, tissue paper.
Abrasive/hard materials: Materials such as sandpaper that can quickly wear down standard sharp blades.
