These solid carbide router bits are experts when it comes to grooving and finishing with exceptionally clean edges. Compression bits of this kind are used not only in CNC nesting machines but also excel in delivering outstanding routing results on router tables. Compared to standard HM groove bits, spiral groove bits have the advantage of transporting wood chips more efficiently thanks to their spiral ground cutting edges.

Features & benefits

  • Finishing router bit made of industrial-quality solid carbide.
  • Z3+3 compression cutting edges: Three edges create a clean groove base (right-hand twist/upcut), while the other three ensure clean and tear-free groove edges (left-hand twist/downcut).
  • When finishing the edge of a workpiece, the combined left- and right-hand twist creates two equally clean routed edges simultaneously. 
  • Materials: softwood, hardwood, and wood-based sheet materials.
