Freud 77-208 Double Compression Bit, 1/2-Inch

Freud

Compression spiral is both up-cut at the bottom (clean floor) and down-cut at the top (clean surface) simultaneously

  • Compression spiral geometry
  • Up-cut at bottom, down-cut at top
  • TiCo Hi-Density carbide
  • For CNC and plunge routing

Pros

  • Compression spiral is both up-cut at the bottom (clean floor) and down-cut at the top (clean surface) simultaneously
  • Produces clean cuts on both faces of a panel -- correct for veneered plywood routed on a CNC or with a plunge router
  • TiCo Hi-Density carbide with Black I.C.E. coating for extended tool life
  • Eliminates the need to choose between up-cut and down-cut when both faces are critical

Cons

  • Higher price than a single-direction spiral bit
  • Primarily a CNC-oriented bit -- requires consistent feed rate for best performance
  • Less common in hand-held plunge routing
