Foam Ball Nose Cutter CNC EPS/EPE Foam Milling Router Bit with Internal Coolant Holes Ball End Spiral Flute

—for 3D Foam Carving, Packaging & Mold Making

Product Description

This foam ball nose cutter is purpose built for high-speed CNC machining of expanded and extruded foam materials — EPS, EPE, PU, EVA, and XPS. Where ordinary woodworking bits dull quickly or melt their way through foam, this cutter is engineered specifically for foam's unique cutting demands: abrasive dust, heat buildup, and the need for tear-free, fuzz-free surfaces.

The precision-ground ball nose tip produces smooth, clean 3D contours with minimal surface fuzz, while the internal coolant holes keep the cutting zone clear of foam debris — eliminating the clogging that plagues standard bits on long foam runs. Finished with a TiAlN-class coating for hardness and heat resistance, this cutter maintains its sharp geometry through extended production, delivering consistently smooth surfaces from the first part to the thousandth.

Product Dimensions

Application

1. Foam Packaging & Mold Making

Cut precise EPS foam molds and packaging inserts for products ranging from electronics to industrial components. The ball nose geometry produces clean cavities and complex 3D shapes ready for molding or direct use.

2. Lost-Foam Casting Patterns

The lost-foam casting process demands clean, accurate foam patterns. This cutter delivers the dimensional accuracy and smooth surface finish required for quality metal castings — patterns that hold their shape through the molding process.

3. Architectural Models & Prototypes

Architectural model makers and product designers rely on clean foam surfaces for presentation-quality models. The fuzz-free ball nose finish minimizes cleanup work on intricate model details.
