Yes, easily. This is a massive advantage over balsa or honeycomb. Foam cores can be machined with woodworking router bits at high speeds.
- Best Practice: Use O-Flute or Upcut Spiral bits to clear chips and prevent melting (especially on PET and HDPE foams).
- Application: 3D shaping of surfboard blanks, mold plugs for concrete casting, and prototyping automotive interior parts.
