  • Specifications can be tailored to meet customer requirements.

Typical Applications

  • Re-cut stage gang rip lines in sawmill production, processing cants and semi-finished timber into boards.
  • Multi-rip machines with and without chippers — Linck, EWD, Möhringer, SAB, Brodbaek, and equivalent.
  • Automated, high-volume longitudinal ripping where stable running across a full blade set is critical.
  • Dimension lumber production requiring consistent strip width and clean side faces.

Key Performance Advantages

  • Re-cut oriented geometry supports stable longitudinal splitting in continuous board production.
  • Thin kerf range (2.7–6.0 mm) helps maximize usable yield from each cant while maintaining practical stiffness.
  • Optional convex-body configurations (b1 up to 6.0 mm) improve rigidity in heavier-duty setups that need stronger anti-deflection behavior.
  • Carbide rakers prevent the steel plate sides from contacting the cut wood face, eliminating scoring, plate heat build-up, and lateral friction wear.
  • High bending strength and carbide hardness maintain edge integrity through extended wet-wood production runs.

Problems This Saw Blade Helps Solve

  • Blade wandering and strip width variation during high-feed re-cut operations.
  • Steel plate contact with the wood face, leading to surface scoring, lateral heat, and premature plate wear.
  • Chip packing in the kerf on wet-wood sawmill lines, causing binding and feed resistance.
  • Short blade life from carbide edges not designed for the combined abrasion of wet fiber and resin in softwood ripping.

Application Notes

  • Match diameter, kerf width, body thickness, and side clearance consistently across all blades in the arbor set.
  • Maintain chip extraction capacity to prevent chip packing, particularly on wet softwood at high feed rates.
  • Regrind on schedule — do not run to heavy wear, as deflection and surface quality deteriorate before edge failure is visible.
