The innovative CNC tool design uses the highest grade carbide insert knife which allows you to get two uses out of each insert. Once the knife shows signs of wear you can rotate the insert for a brand new cutting edge. These industrial V-Groove insert router bits were especially designed for applications including:

  • Miter folds - "create the perfect joint"
  • Signmaking and lettering

Excellent for cutting:

  • Aluminum, Brass, Bronze, Copper, Gold, Silver & Carbon Fiber
    (Engraving Only)
  • Acrylic/Plastic
  • Composites
  • Composite Decking
  • Epoxy (Epoxy Resins)
  • Foam
  • High Density Polyethylene (HDPE)
  • Laminate
  • Melamine
  • PVC
  • Sign Board
  • Solid Surface
  • Veneered Plywood
  • Wood
  • Xanita® Board*
  • 20lbs High Density Urethane

*When working with Xanita LightBoard panel (X-board® X-board® plus) we recommend using MDF knives for better results.

Advantages of Insert Tooling:

  • Long lasting insert knives provide superior smooth quality cuts every time
  • Quick and precise replacements of dull knives
  • Due to insert accuracy tool life is extended
  • Insert tooling allows for harder grades of carbide
  • Special carbide grades for special applications
  • Cost effective solution compared to replacing brazed router bits

Secure locking screw system ensures maximum safety and maintains cutting accuracy. CNC router requires quality hold downs to ensure the least possibility of material shifting during operation.

Warning: Before using any insert tool, make sure the set screw is tightened firmly. When replacing a dull insert, first clean the tool and remove all dust prior to inserting the new knife.

What’s the optimum cutting parameters for this tool?
Question by: Rich Billington on Dec 12, 2019, 2:43 AM
Thank you for the question.

On this tool I would recommend a starting RPM of 16,000. A feed rate of 75” per minute with a minimum of 3 to 4 passes. Watch the cuts and increase and or decrease your RPM and or feed rate in 10% increments.
