How Buyers Describe and Specify This Blade
Industrial teams often use several names for the same blade family. We use those terms to identify the likely application, then confirm the final design from the drawing, sample and machine conditions.
Size and geometry. The terms “three-hole industrial razor blade”, “thin carbide slitting blade” and “carbide foil cutting knife” usually describe geometry or configuration. Requests using “precision three-hole slitter blade” or “custom hole-position foil blade” should confirm critical dimensions and edge orientation.
Application and equipment. Buyers may search for “tungsten carbide foil slitter blade”, “precision knife for thin metal foil cutting” or “battery electrode foil cutting knife” when identifying an application. For requests described as “aluminum foil slitting knife” or “copper foil slitter blade”, include the processed material, machine interface and required cut quality.
Custom and replacement supply. Sourcing language can include “thin foil cutting razor blade”, “three-hole blade for slitter rewinder” or “replacement foil blade for converting machine”. Requests using “custom three-hole blade manufacturer” or “OEM foil blade from drawing” should include an approved drawing or sample details before production.
The approved drawing and application conditions always control the manufactured blade specification.
How to Specify a Tungsten Carbide Foil Slitter Blade
- Confirm blade length, width, thickness, three-hole spacing and locating tolerances.
- Describe the foil material, thickness range, slitting method and required edge quality.
- Provide the holder or machine model and identify the working edge and cutting direction.
- Report burr, edge-chipping, dust or service-life problems from the current blade.
