Sinajet decagonal and multi-sided rotary knife blades are high-performance industrial tools designed for precision digital cutting systems. While standard "decagonal" blades have 10 sides, Sinajet also utilizes high-edge-count variants, such as 16-sided (hexadecagonal) blades, to provide an even smoother cutting action and more fresh edges per rotation.

Key Specifications

These blades are primarily crafted from tungsten carbide, which provides extreme durability and edge retention—lasting significantly longer than standard steel.

Common Models: Y10, Y17, Y24, and Y33 are the primary Sinajet series for rotary modules.

Dimensions:

 Outer Diameter: Typical sizes include 25mm, 28mm, 32mm, and 38.5mm.

 Inner Diameter (Bore): Standard mounting is 8mm or 6mm, depending on the specific tool head.

Thickness: Generally around 0.63mm.

· Edge Count: Options include 10-sided (standard decagonal) and 16-sided (high-precision) configurations.

Applications and Material Compatibility

Sinajet rotary blades are engineered for active circular knife solutions, which prevent "overcutting" and are ideal for materials that might bunch or snag under a static drag knife.

· Textiles & Apparel: Woven fabrics, nylon, polyester, and delicate silk.

· Composites: Carbon fiber, glass fiber, and aramid (Kevlar) fabrics.

· Industrial Materials: Leather, felt, PVC, EVA foam, and vinyl.

· Specialty Items: Carpet, advertising light sheets, and corrugated cardboard.

Compatible Machines

While specifically designed for Sinajet digital cutters (such as the DG and DF series), these blades often feature universal mounting dimensions compatible with other CNC systems.

Native Equipment: Sinajet DG 1216, Sinajet DG 2516, and other Changzhou Sinajet flatbed systems.
