Reversible Planer Knives for TERSA Systems

Reversible Planer Knives “TersoTri” for TERSA® Systems

Stable, precise, and economical for daily planing operations

Looking for Tersa planer knives for your planing machine? Our TersoTri reversible planer knives fit all standard Tersa® system cutterheads—from 300 through 410 and 510 to 520 and 630 mm, plus 60- and 120-meter rolls for custom lengths. Perfect fit and precision, ready to use, 99% available from stock.

Our TersoTri knives are manufactured using Trimetall technology. They have a three-layer sandwich construction, with only the middle layer being soft and flexible, while the two cutting edges are made of ultra-hardened HSS-M42 material (24%). The edges feature a mirror-polished bevel and a polished back bevel, resulting in a significantly better planing finish and longer tool life.

Advantages

  • Perfect fit and precision
  • Smooth, clean wood surfaces due to maximum sharpness and high resistance to chipping
  • Longer tool life due to extreme edge hardness and 33% higher alloy content in TriHSS-M42 compared to standard HSS steel
  • Higher break resistance due to the soft core
  • Excellent price-performance ratio
  • Available in fixed lengths as well as 60 or 120-metre rolls
  • Also available in the following grades: TerSolid with high chrome content and TersoCarb carbide

Looking for a matching cutterhead? Our TersoTri cutterheads are Tersa-compatible and can be loaded with centrifugal clamping without setting aids.
