Four Flute End Mill – Definition & Overview
A four flute end mill is a high-efficiency metal cutting tool designed for precision milling operations. Its four helical flutes optimize chip evacuation and cutting stability, making it ideal for slotting, contouring, and face milling of steel, stainless steel, aluminum alloys, and other materials. Compared to two-flute end mills, the quadruple cutting edges deliver 40% higher feed rates and superior surface finish (Ra0.4μm), serving as essential CNC tools for productivity improvement and cost reduction.
Core Advantages
① Superior Chip Evacuation
30°-45° helix angle creates continuous chip channels, preventing clogging in deep-slot milling (up to 8×D) and high-speed machining (HSM) applications.
② Extreme Rigidity & Vibration Control
Reinforced core diameter + submicron carbide substrate (HRA93.5 hardness) reduces vibration and extends tool life by 300% versus standard end mills.
③ Precision Surface Quality
Asymmetric flute spacing eliminates harmonic vibration, achieving Ra0.4μm surface finish – ideal for vertical wall finishing without secondary polishing.
④ Universal Compatibility
- Materials: 6061-T6 aluminum → HRC55+ tool steels
- Machines: CNC centers & turn-mill complexes
- Cooling: Dry cutting / MQL / Through-Tool Coolant Ports
⑤ Advanced Wear Resistance
TiAlN/TiCN nano-composite coatings + ultra-fine grain carbide increase heat resistance by 200%, with custom flute lengths/geometries available.
