Zünd introduces new DLC-coated router bits to improve efficiency

Zünd announces a new DLC-coated router bits. The coating reduces friction and increases wear resistance, thereby delivering very high-quality results as well as better performance and cost efficiency. The new router bits are especially beneficial in routing applications involving aluminium, aluminium composites, wood, and PVC. Friction and wear during the routing process substantially affect the quality of cut parts, routing performance, and longevity of bits. Thin-film coatings are among the most effective ways to achieve significant improvements in performance and productivity.

Innovative DLC (diamond-like carbon) coating permits greater processing speeds and cutting depths. The number of passes can be reduced, which significantly increases routing productivity. Up to 4 mm thick aluminium composites can be processed in a single pass, at speeds of up to 11 m/36 ft per min. In many cases, a finishing pass becomes unnecessary, which further reduces production time. The new bits are optimized for use with Zünd routing spindles and are available in diameters from 2 to 6 mm and for routing depths up to 22 mm/.87 in. They are also available with stop ring, which makes them suitable for use with the automatic tool changer ARC.
