Solid Carbide End Mill 3.0mm 4-Flute HA Shank TS 440N Series

Precision machining of steel, cast iron, and non-ferrous metals demands a cutting tool that balances sharpness, rigidity, and wear resistance. This solid carbide end mill with a 3.0 mm cutting diameter and 4 flutes delivers exactly that, enabling clean slotting, profiling, and contouring in materials up to 440 N/mm² tensile strength.

Who is it for

CNC machinists, toolmakers, and production engineers who require a reliable general-purpose end mill for daily milling operations. It is particularly suited for workshops handling a mix of steels, cast irons, and aluminium alloys where tool changes must be minimal.

Tips

For best results, use a rigid tool holder with minimal runout and apply appropriate coolant or air blast to evacuate chips. When machining steels near the upper tensile strength limit, reduce cutting speed slightly and ensure adequate feed per tooth to avoid work hardening.
