Nanjing Costar Precision Tools Co.,Ltd. produces a tungsten carbide three‑holes razor blade designed for high‑precision film slitting. The blade body is forged from WC carbide and is supplied in two size series: 43 × 22 × 0.1 mm, 43 × 22 × 0.15 mm, 43 × 22 × 0.2 mm, 43 × 22 × 0.3 mm, and 57 × 19 × 0.4 mm. The three‑hole mounting pattern provides stable attachment to slitter shafts, reducing vibration during continuous runs. The listing does not disclose MOQ or price, allowing flexible order volumes.
In the flexible‑film conversion sector, blades of this type typically exhibit a hardness of 1700‑1900 HV and a grain size near 0.4 µm, delivering a clean cut with minimal burr on materials such as LLDPE, PP, PET and BOPP. Standard edge angles of 30° are common, and a TiAlN coating is often applied to extend tool life under high‑speed operation. Dimensional tolerances of ±0.02 mm on thickness and ±0.05 mm on width are customary to maintain consistent slit width across production runs.
These blades are used by packaging converters and film manufacturers that require precise, repeatable cuts for labels, stretch film and metal‑film laminates. They are typically shipped FOB from Chinese ports such as Shanghai or Ningbo, with the possibility of CIF terms if requested. Importers should verify the exact blade dimensions, coating option and any required certification before confirming a purchase.
