Our 3mm 4-flute solid carbide end mill is engineered for high-precision machining in steel (up to HRC55), aluminum, and other engineering materials. Manufactured from ultra-fine micro-grain tungsten carbide (0.5μm grain size) with advanced TiAlN coating, this precision cutting tool delivers exceptional wear resistance and thermal stability in demanding CNC applications. The optimized 4-flute design provides perfect balance between material removal rate and surface finish quality.
Advanced TiAlN coating (3-4μm thickness) for high-temperature operations
Precision ground cutting edges with ±0.003mm tolerance
35° helix angle for smooth chip evacuation
1/8" (3.175mm) shank with h6 tolerance
Special edge preparation for improved edge retention
Mirror finish flute surfaces (Ra 0.1μm) for aluminum applications
Performance Advantages
5* longer tool life than standard carbide end mills
