Turnover planer knives for TERSA systems
Stable, precise, and economical for daily planing operations
Our TersoTri knives are manufactured using tri-metal technology. They consist of three parts (sandwich-like), where only the middle part is soft and flexible. Both cutting edges, however, are made of high-hardened HSS-M42 material (24%). The edges feature a mirror-polished finish and a polished counter-grind, resulting in a significantly better planing finish and longer tool life.
Advantages

- Available in fixed lengths as well as 60 or 120-meter rolls
