Product Description: The 390-550 is a high-performance 60° tangential knife blade precision-manufactured from high-density tungsten carbide. Specifically engineered for Summa T-Series cutting heads, this blade is designed for the rigorous demands of tangential cutting, where the blade is actively rotated by the machine to maintain perfect orientation through complex paths and thick substrates.

With a steep 60° angle and a maximum cutting depth of 1.20 mm, the 390-550 is the definitive tool for processing tough, heavy, or multi-layered materials that standard blades cannot penetrate cleanly. It is highly optimized for technical media, including high-intensity reflective foils, magnetic vinyl, and thick masking films used in sandblasting applications. The 3.0 mm round mounting shank ensures perfect alignment within the tangential tool holder, while the 2.5 mm blade diameter provides the mechanical strength required to navigate dense materials without snapping. Crafted from premium carbide, this blade delivers exceptional wear resistance and maintains a razor-sharp edge through extended production runs of abrasive reflective and metallic substrates, ensuring burr-free, professional-grade results.
