  • Planing large glued up panels using CNC
  • Surfacing and finishing wood using timber slab machines
  • Rabbeting or slotting

These industrial router bits comes complete with four (4) MDF-Grade solid carbide insert knives, each with four (4) cutting edges that allow users to rotate the knife when one side becomes dull. Designed for spoilboarding, planing & rabbeting large surface areas in the following materials:

  • MDF
  • Fiberboard
  • High Density Urethane (HDU Board)
  • Balsa Core*
  • Plastic*
  • Solidwood/Softwood*
  • Plywood/Chipboard*
  • Ultra-High-Molecular-Weight Polyethylene (UHMWPE)

Max RPM #RC-2252 = 18,000

The RC-2252 industrial router bit used in conjunction with the Amana Tool® Straight Plunge 45200 to square out the corners make production of MDF Shaker-style doors economical and less labor-intensive, while producing superior results.

Recommendations: For surfacing solid woods it is recommended to remove both bottom scorers.
