| High Light | 0.5mm Ultra-Thin Tungsten Carbide Circular Slitting Blade ，17° V-Edge Tungsten Carbide Circular Slitting Blade ，Ø60mm Tungsten Carbide Circular Slitting Blade | ||
In precision slitting and micro-cutting applications, tool thickness and blade geometry determine the quality of the cut and the yield of the final product. This Ø60mm tungsten carbide circular slitting blade is engineered to meet the most demanding precision cutting requirements. With an ultra-thin 0.5mm thickness and a highly specialized 17° V-shaped cutting edge (with a 1.66mm cutting depth), it delivers exceptionally clean cuts with minimal kerf loss and burr formation.

| Edge Quality | Sharp, V-shaped profile, burr-free |
| Industry | Application | Why This Blade |
|---|---|---|
| Battery Manufacturing | Slitting of lithium-ion battery electrodes (cathode/anode foils), separator films | Ultra-thin 0.5mm profile minimizes material waste; mirror finish prevents particle adhesion |
| Electronics | Cutting of copper foil, aluminum foil, flexible printed circuits (FPC), and shielding materials | 17° V-edge provides clean, burr-free cuts; high precision ensures component integrity |
| Packaging & Films | Precision slitting of BOPP, PET, PVC, and other thin films | Minimal kerf loss; extended blade life in high-speed slitting operations |
| Medical Devices | Cutting of medical films, transdermal patches, and diagnostic strips | Cleanroom compatible; mirror finish meets hygienic requirements |
| Specialty Tapes | Slitting of adhesive tapes, protective films, and conductive tapes | Ultra-thin profile prevents adhesive buildup; clean edge ensures consistent tape width |
| Metal Foils | Precision slitting of thin metal foils (copper, aluminum, brass) | HRA 91–92 hardness withstands abrasive metal foil cutting |
This ultra-thin circular slitting blade is manufactured through a rigorous, multi-stage process to ensure the highest precision:
This blade is designed for precision slitting and micro-cutting applications. Its ultra-thin 0.5mm profile and 17° V-edge make it ideal for slitting battery electrodes, copper foils, films, tapes, and other thin materials where minimal kerf loss and clean cuts are essential.
The ultra-thin 0.5mm thickness minimizes kerf loss (material waste) and reduces cutting forces. This is critical for high-value materials such as battery electrode foils and thin films, where maximizing material yield is essential.
The 17° V-shaped cutting edge concentrates cutting force for clean shearing and separation with minimal deformation of the workpiece. The precise edge geometry (with a 1.66mm edge distance) ensures consistent, burr-free cuts.
This formulation provides an ideal balance of hardness (for wear resistance and edge retention) and toughness (to prevent edge chipping in thin-blade applications). HRA 91–92 is significantly harder than tool steel (typically HRC 58–62), delivering 10–30× longer service life.
