Zund Z50 rotary blade knife 3910335 – replacement

The Zund Z50 Rotary Knife – 3910335 (replacement) is a precision, ten-sided rotary knife made of cemented carbide, fully compatible with Zünd (S3, G3, L3), Humantec, and Lectra MFC cutting plotters. The 25mm diameter blade, with a 36° angle and a maximum cutting depth of 5mm, is designed for efficient and clean cutting of fibrous materials such as technical fabrics, aramid, carbon, and glass fibers, as well as felt and non-woven fabrics. It's a reliable alternative to the original blade, ensuring long life and ideal for advanced production, minimizing fraying and increasing cutting precision.

Additionally, the blade can be covered with specialized protective coatings that increase its durability and improve its working properties:

• DLC (Diamond-Like Carbon) – an ultra-hard, black carbon coating with a very low coefficient of friction that significantly extends blade life, reduces wear, and protects against corrosion. Ideal for cutting difficult, fibrous, and abrasive materials.

• TiN (Titanium Nitride) – a gold-colored ceramic coating with high abrasion and temperature resistance. It improves blade durability, reduces friction, and provides an attractive appearance, serving as both a practical and decorative solution.

Thanks to the possibility of using these coatings, the Zund Z50 knife becomes even more resistant to intensive use, staying sharp for longer and ensuring the highest cutting quality in demanding production processes.
