JWEI J314 J324 J385 J373 point slotter blade tungsten carbide knife industrial drag round blades

JWEI (Jingwei) CNC digital cutting machines utilize specialized tungsten carbide (Widia) knife blades designed for high-performance industrial processing. Each model number corresponds to a specific thickness, geometry, and mechanical cutting system (oscillating, drag, slotting, or rotary/round) to handle specific types of soft and semi-rigid packaging, advertising, and textile substrates

The JWEI J314, J324, J385, and J373 point slotter blades are high-performance industrial tools designed for precision cutting tasks. These blades are crafted using durable tungsten carbide material, ensuring long-lasting sharpness and exceptional wear resistance. Specifically engineered for drag cutting applications, the round blades offer superior reliability and consistent performance in demanding work environments. Ideal for various industrial uses, these tungsten carbide knives ensure accuracy and efficiency, making them a valuable addition to any professional cutting operation.

Key Material Properties

Solid Tungsten Steel Carbide: Manufactured using ground virgin alloys to guarantee exceptional heat and wear resistance under high mechanical stress.
Industrial Drag & Slotting Optimization: Razor-sharp edges generate clean, burr-free cuts along heavy cardboard scorelines and flexible polymer paths.
High Production Efficiency: Outlasts high-speed steel (HSS) equivalents, greatly dropping blade replacement down-time in large industrial print and packaging houses.
