CNC foam tools let you achieve depth and precision for thick foam carving applications. Ensure your foam projects are milled with accuracy and high detail, deep cuts in thick materials in fewer passes. For thick material up-cut chip removal.

  • Great for deep profiling

For use in CNC routers and CNC router systems for machining foam.

Excellent for cutting:
  • Acrylonitrile-Butadiene-Styrene (ABS)
  • Aluminum Alloys
  • Crosslinked Polyethylene Foam (XLPE)
  • Ethafoam**
  • Ethylene-vinyl Acetate Foam (EVA)
  • Expanded Polypropylene (EPP)*
  • Expanded Polystyrene (EPS)
  • Extruded Polystyrene Foam (XPS)
  • Flexible Polyurethane Foam (FPF)
  • Foam
  • Fomex®
  • Polycarbonate (Lexan™)
  • Plastics
  • Polyethylene Foam**
  • Polylam**
  • Polyurethane Foam
  • Wood

*Expanded polypropylene (EPP) is a foam form of polypropylene.

**Ethafoam Polyethylene and Polylam are durable flexible closed-cell foams with excellent memory.

Recommendation: Use the slowest suggested feed rates and the shortest bits necessary for cutting and routing Lexan™.

Titanium Nitride (TiN) coating increases strength and durability. TiN coated router bits harden and protect the cutting edges in addition helps smooth the flutes for improved chip ejection.
