Product Description: The 390-534 is a high-precision 36° tangential knife blade, engineered for the demanding requirements of Summa T-Series cutting systems. Unlike standard drag knives, this tangential blade is actively controlled by the machine’s motor, ensuring the cutting edge is always perfectly oriented to the cutting path. This makes the 390-534 an essential tool for high-accuracy work on thin, technical substrates where edge quality is paramount.

With a shallow 0.25 mm maximum cutting depth, this blade is specifically optimized for precision kiss-cutting. It allows for the clean separation of top-face materials—such as self-adhesive vinyls, polyester fabrics, and reflective foils—without marking or penetrating the carrier liner. The 36° angle provides a sharp, delicate point ideal for intricate detailing and small-format text. Constructed from high-density tungsten carbide, the 390-534 offers superior wear resistance compared to steel alternatives, maintaining its razor-sharp edge through long production cycles. The 3.0 mm round mounting shank ensures a secure, vibration-free fit in the tangential tool holder, delivering the professional-grade stability required for complex digital finishing tasks.
