jingwei (JWEI) J378 is an industrial-grade, solid tungsten carbide rotary knife blade engineered specifically for high-speed motorized rotary tool modules (RCT/DRT) on JWEI CNC digital flatbed cutters.

Designed for processing soft, flexible, and high-density fibrous materials without snagging or edge fraying, the J378 model offers superior thickness and structural stability for demanding industrial production runs.

Technical Specifications

With a thickness of 1.5 mm (compared to the 0.63 mm or 1.0 mm thickness of rotary blades such as the J373 or J376), the J378 is designed for high-resistance substrates where blade deflection can cause the cut line to deviate.:

• Heavy Textiles & Canvas: Multi-layered woven fabrics, synthetic awnings, Kevlar, and technical filter media.

• Leather & Fur: Heavy natural leather hides, artificial leather, and dense plush materials.

• High-Density Foam & Felt: Thick industrial felt pads, EVA/EPE foam layers, and gasket materials.

• Floor Covering & Rubber: Thin rubber matting, carpet, and non-woven floor coverings.
