4 Flute Carbide U-Slot End Mill for Steel Stainless Inconel High Efficiency Roughing Finishing
Introduction:
Our 4-flute U-slot carbide end mill is engineered for high-performance machining of tough materials like steel (HRC 50+), stainless steel, and Inconel. Featuring an optimized U-groove geometry and ultra-fine grain carbide, this tool delivers exceptional material removal rates in roughing while maintaining precision finishes—ideal for dynamic milling, mold/die, and aerospace applications.
Features:
✔ 4-Flute U-Slot Design – Balances chip evacuation and surface finish.
✔ Solid Carbide Construction – 3X longer life vs. HSS tools in Inconel.
✔ High Helix (35°) – Reduces cutting forces in stainless/gummy alloys.
✔ TiAlN/AlCrN Coating – Withstands 1,000°C (optional).
✔ Precision Ground – ±0.01mm tolerance, <0.005mm runout.
✔ Size Range – 3mm-20mm (1/8" to 3/4"), custom lengths available.
Advantages:
✅ 50% Faster Machining – High feed dynamic milling compatible.
✅ Burr-Free Finishes – Ra 0.4μm achievable in finishing passes.
✅ Reduced Vibration – Balanced design for deep slot stability.
✅ Multi-Material Ready – Steel (4140, H13), Stainless (316), Inconel 718.
✅ Through-Coolant Option – For high-heat alloys.
