Product Description: The Type 3 (Part Number: 3910303) is a robust, professional-grade drag blade engineered for high-demand textile and flooring applications on Zund digital cutting systems. Manufactured from premium High-Speed Steel (HSS), this blade is specifically designed for environments where material toughness requires a blade that balances extreme edge sharpness with high fracture resistance.

Functionally similar to the Z11 blade, the Type 3 is distinguished by its enhanced life expectancy and a larger overcut geometry, making it a superior choice for high-speed automated workflows. The double-edged design allows for maximum utility and efficient cutting of dense, fibrous materials. With a dual-rated maximum cutting depth of 2.4 mm and 7.9 mm, it is exceptionally well-suited for processing industrial carpets and heavy polyester fabrics. Designed for seamless integration with the SCT (Speed Cut Tool) and UCT (Universal Cut Tool), the 0.63 mm flat-stock mounting ensures a precise, stable fit, delivering clean and accurate cuts through the most challenging soft-floor and textile substrates.
