Rennie Tool Company - 12mm x 200mm Flute Foam Cutting HSS Ball Nose Router Cutter – Long Reach CNC Milling Bit for EPS Foam, Polystyrene & Lightweight Materials. 4 Flute Spiral Up Cut Router Bit

• Recommended Speed – 6000 RPM
• 12mm Ball Nose (6mm Radius) ideal for 3D CNC carving and precision contouring
• 200mm cutting length with 250mm overall long reach design for deep cavity machining
• Manufactured From HSS for clean cutting in EPS foam polyurethane PU EVA polyfoam and styrofoam
• Perfect for CNC foam mould making signage prop building pattern work and model production

This long series / extra long series HSS ball nose foam router cutter is engineered for professional CNC machining of EPS and lightweight materials. Designed for extended reach applications, it allows deep cavity cutting, large-scale 3D carving, and precision contouring where standard router bits cannot reach. Ideal for use on CNC routers, robotic milling machines, and large format CNC machining centres, this ball nose end mill delivers smooth surface finishes and accurate profiling in expanded polystyrene (EPS), polyurethane foam, polyfoam, EVA foam, modelling board, and plastics. The precision ground ball nose tip is perfect for 3D CNC carving, foam mould production, plug manufacturing, architectural models, signage fabrication, stage props, composite tooling, and pattern making. Its long cutting length makes it especially effective for deep foam cutting and large object machining. Manufactured from high speed steel (HSS), this foam milling cutter provides sharp cutting performance, efficient chip evacuation, and clean material removal in low-density substrates.
