Blade Materials: HSS vs Tungsten vs Standard Steel
Material choice determines sharpness, durability, and cost:
• High-Speed Steel (HSS): Balanced sharpness and price, ideal for most cutting tasks.
• Tungsten Steel: Offers superior hardness and long life, ideal for large-volume production.
• Standard Steel: Budget-friendly, best for low-duty use or temporary replacement.
Brand Compatibility and Common Mistakes
Each machine brand has specific blade specs. For example, Polar blades have standardized length and hole patterns. Buying incompatible blades can lead to quality issues or equipment damage. PrintingMates offers precise-matching blades for Polar, Wohlenberg, Perfecta, and more.
