Customized sizes are available, according to your drawing or sample.
The film slitting blade is a circular shear knife designed for clean, burr-free cutting of plastic films, laminates, and flexible packaging webs on slitter rewinders and converting lines. For metal, foil, and non-woven slitting applications requiring higher hardness grades, see our rotary slitter knives. Available in standard dimensions such as 610×68.3×3.8mm, 610×68.3×4.76mm, and 610×82.55×3.8mm, with custom outer diameters exceeding 1000mm on request. Manufactured from D2 (Cr12MoV), M2 high-speed steel, or equivalent grades, these blades achieve HRC 58–64 after vacuum heat treatment and cryogenic processing, delivering the edge stability required for high-cycle, thin-gauge film slitting.
Hardened to HRC 58–64 with a uniform microstructure, reducing micro-chipping and extending service intervals in continuous film lines.
Stocked in 610mm OD configurations; custom blanks can be ground to outer diameters of 1000mm or more for wide-web slitter rewinders.
Offered in D2 (Cr12MoV) for abrasive films, M2 HSS for high-temperature stability, and other grades matched to specific web materials.
Blade thickness is held to ±0.005mm with parallelism within 0.003mm, ensuring consistent shear gap and minimal web deflection.
Bores machined to H7 tolerance with optional keyways, pin holes, or drive slots to match OEM knife holders from Dienes, Tidland, or others.
We offer a variety of standard sizes, including 610x68.3x3.8mm, 610x68.3x4.76mm, and 610x82.55x3.8mm, among others. Additionally, we can accommodate custom specifications, including outer diameters of 1000mm or more. For more details, please reach out to our customer service team. We look forward to connecting with you!

YISHI Machinery produces film slitting blades from vacuum heat-treated D2 and M2 tool steels, with in-house grinding to Ra ≤0.2µm and thickness tolerances of ±0.005mm. We accept single-piece custom orders and provide full dimensional inspection reports. Our blades are compatible with major slitter rewinder brands, and we offer expedited production for replacement knives. Every blade is edge-protected and individually packaged to prevent transit damage.
For abrasive films such as metallized BOPP or filled PE, D2 (Cr12MoV) at HRC 60–62 offers excellent wear resistance. For high-speed lines where frictional heat is a factor, M2 HSS provides better hot hardness and edge stability.
Yes. Provide your OEM holder model or a dimensional drawing, and we will machine the bore to H7 tolerance with the required keyway, pin holes, or drive slots.
The MOQ is 1 piece. We manufacture single custom blades to your drawing or sample, with no tooling charges for standard material grades.
All blades are double-disc ground and inspected on a coordinate measuring machine. Parallelism is held within 0.003mm, and OD runout relative to the bore is ≤0.01mm.
Standard ground finish is Ra ≤0.2µm. A mirror-polished finish is available for films sensitive to drag or static build-up.
