Jingwei Jwei J374-B 16-Sided (Hexadecagonal) Tungsten Carbide Rotary Cutting Knife Blades

JingWei (JWei) J374-B is a specialized tungsten carbide rotary knife blade specifically engineered for 16-sided (hexadecagonal) geometry, optimizing high-speed fabric shearing on industrial CNC digital cutting tables.

Technical Specifications
Outer Diameter: 32.00 mm
Bore/Mounting Hole Diameter: 8.00 mm
Thickness: 0.60 mm to 0.63 mm
Cutting Angle: 36°
Maximum Cutting Depth: 7.00 mm (highly effective for materials up to 5mm thick)

While the standard J374 is a decagonal (10-sided) blade, the "B" variation (J374-B) bumps the facet count up to 16 sides to deliver an even smoother, near-circular rolling action while preserving discrete micro-shearing edges.

Material Composition: Premium solid tungsten carbide / cemented carbide (Hardness: ~89–92 HRA), ensuring exceptionally long runtime without edge degradation.
Target Applications & Material Compatibility
The 16-sided faceted design provides miniature "shredding" and micro-slicing actions that prevent high-strength fibers from pulling, snagging, or bunching under the tool head. It is widely used to process:
Advanced Composites: Aramid fibers (Kevlar), carbon fibers, and glass fibers.
Industrial Textiles: Tough nylon, dense polyester, non-woven fabrics, and heavy-duty felt.
Flexible Synthetics: Technical apparel textiles, flexible transparent PVC, and light carpeting.
Machine Compatibility
These blades are primarily used on JingWei (JWei) CNC digital flatbed cutters equipped with active rotary motorized tool heads (such as the JWei FH03II textile series). Due to standardized 32mm x 8mm dimensions, they are also frequently compatible with other automated flatbed textile cutting systems from brands like iCHO, AOL, AOKE, or New Bull.
