This long series / extra long series HSS square end foam router cutter is designed for precision CNC machining of EPS and other lightweight materials. Featuring a flat end cutting profile, it is ideal for producing sharp edges, flat surfaces, clean steps, and straight wall cavities in foam blocks and modelling materials. Engineered for extended reach applications, this long reach CNC router bit allows deep foam cutting and large-scale machining where standard length tools cannot reach. Perfect for use on CNC routers, robotic milling systems, and large format CNC machines. The square end geometry is particularly suited for: Flat bottom pockets Step cutting Straight edge trimming Block profiling Slotting and cavity machining Optimised for expanded polystyrene (EPS), styrofoam, polyurethane foam, polyfoam, EVA foam, modelling board, and certain plastics, this foam milling cutter ensures efficient material removal and smooth finishes in low-density substrates. Manufactured from high speed steel (HSS), it offers reliable cutting performance, durability, and clean chip evacuation during high-speed CNC foam routing. Suitable For: EPS foam cutting Styrofoam machining PU and polyurethane foam routing CNC foam mould production Foam plug manufacturing Architectural models Sign making and lettering Large 3D CNC foam projects Robotic foam milling A professional long reach square end CNC router cutter built for deep cavity machining, precision foam shaping, and industrial-scale foam processing.
