Product Description: The 391-231 is a specialized 60° drag knife blade precision-manufactured from high-density tungsten carbide. Engineered for Summa digital cutting systems, this blade is designed for applications requiring a combination of extreme sharpness and a steep angle to navigate complex geometries in challenging substrates.

With its 60° cutting angle, this blade is the definitive choice for processing thick or high-intensity materials that standard 36° or 45° blades may struggle to penetrate cleanly. It is specifically optimized for technical films, including reflective vinyl, magnetic foils, and heavy masking films. The 0.50 mm maximum cutting depth allows for precise control in multi-layered or backed materials, ensuring the face film is severed without damaging the liner. The 1.50 mm blade diameter combined with a 2.00 mm mounting profile ensures a secure and stable fit in the tool holder, minimizing vibration during high-speed plotting. Constructed from premium carbide, the 391-231 offers exceptional wear resistance and edge stability, maintaining a razor-sharp finish through long production cycles of abrasive reflective and metallic media.
