Industrial-Grade Cutting Performance

The 12mm 4-Flute Carbide End Mill is an industrial-grade cutting tool designed for high-performance machining of tough materials including stainless steel (17-4PH), tool steels, and alloy steels. Built from ultra-fine grain tungsten carbide (YG10X) and featuring an optimized 4-flute geometry, this end mill delivers exceptional metal removal rates (MRR), tool life, and surface finish quality in demanding CNC applications.

Key Features
  • Industrial Carbide Construction (YG10X Grade)
    • Sub-micron grain structure for maximum edge retention
    • 5-8X longer life vs. HSS end mills
    • Withstands high cutting temperatures without deformation
  • 4-Flute High-Efficiency Design
    • Balanced chip load for stable cutting in steels
    • Variable helix (35°/40°) reduces vibration & harmonics
    • Large core diameter for rigidity in heavy cuts
  • Premium Coating Options (Optional)
    • AlTiN Coated Version available for HRC≤55 materials
    • TiSiN Nano-Coated Version for gummy stainless steels
    • Uncoated for general purpose applications
  • CNC-Optimized Performance
    • Precision ground to ±0.008mm tolerances
    • G2.5 dynamically balanced for 15,000+ RPM
    • Coolant-through capability (optional)
  • Flat Bottom & Corner Radius Options
    • True flat bottom for shoulder milling
    • R0.5 corner radius available for edge strengthening
Performance Advantages
Higher Productivity - 30% faster feed rates vs. 3-flute designs
Superior Finish - Ra 0.4-0.8μm achievable in finishing passes
Vibration Damping - Variable helix eliminates chatter marks
Deep Cutting Capable - Stable performance at 2.5xD depth
Cost Efficiency - Reduced tool changes lower per-part cost
Recommended Applications
Materials:
  • Stainless Steels: 17-4PH, 304, 316
  • Tool Steels: D2, H13, A2 (HRC≤55)
  • Alloy Steels: 4140, 4340
  • High-Temp Alloys: Inconel 718, Waspaloy
Industries:
  • Aerospace (structural components, landing gear)
  • Medical (surgical instruments, implants)
  • Oil & Gas (valve bodies, wellhead components)
  • Mold & Die (core/cavity machining)
Operations:
  • Shoulder milling
  • Pocketing
  • Contouring
  • Slotting
  • Face milling
