Trex Groove Cutter

Trex Groove Cutter


Traditional square edge boards require traditional top fixing deck screws for installation; however, using a Trex groove cutter routes the necessary edge groove into any square edge board to accommodate our hidden fastening system. This can be very handy on the back side of a mitred boarder (picture frame) decking board.

For use on any Trex decking board. Not suitable on 19mm thick fascia board.


  • Quality sealed bearing for guidance and avoiding burn marks.
  • 3 flute design for cleaner faster cutting.
  • 6.4mm shaft will suit all router machines
  • High quality tungsten carbide construction for longevity
  • Comes in a storage box with a clear lid for easy bit identification


To reduce the risk of injury, user must:

  • Always wear proper protective clothing (safety goggles, gloves, dust mask etc.)
  • Read enclosed Trex instructions for proper set-up.
  • Read router operating instructions.
