Benefits of the in-Tech™ Series include:

  • Cutting accuracy remains constant during the life of the knife
  • Priced comparably to brazed router bits with at least 4 times longer tool life
  • Superior cutting quality
  • No sharpening costs
  • Harder grade tungsten carbide


Replacement insert knives sold as a pair.
