Import Coil Slitting Solid Carbide Blades Round Knives — Buy in wholesale FOB from Supplier in China

These solid carbide round knives are precision-ground cutting tools designed for high-speed slitting of flexible materials such as paper, film, cardboard, and non-woven fabrics. The blades feature a hardness of 90-92 HRA, with diameters ranging from 20 mm to 150 mm and thicknesses from 0.8 mm to 3.0 mm, as specified in the source data. Edge geometry is optimized for clean cuts with minimal burr, and all blades are manufactured using tungsten carbide grade YG8 or equivalent, with cobalt binder content of approximately 8%.

The material composition aligns with standard industrial grades for slitting applications, where YG8 offers a balance of wear resistance and toughness suitable for continuous operation on converting lines. Typical tolerances for diameter are ±0.02 mm and for thickness ±0.01 mm, consistent with industry norms for precision carbide blades. Surface finish is ground to Ra ≤ 0.2 μm to reduce friction and material buildup during high-RPM operation. These blades are not coated but rely on the inherent hardness of the carbide substrate for longevity.

They are used on slitting machines from manufacturers including BHS, FOSBER, ISOWA, and Mitsubishi, primarily in packaging, printing, and textile industries. Buyers typically order in batches of 10 to 100 pieces depending on production volume. Packaging is individual foam-wrapped in rigid cardboard boxes, with custom labeling available. Lead time is typically 7 to 14 days after order confirmation, and shipping is handled via DHL, UPS, or FEDEX. MOQ and exact pricing must be confirmed directly with the supplier.
