4 Flute Variable Helix Carbide End Mill Mold Steel Machining with
TiAlN Coating
Introduction:
Our 4-flute variable helix carbide end mill is engineered specifically for high-performance mold steel machining, delivering exceptional efficiency and precision in demanding
applications. Featuring an advanced TiAlN coating and variable helix geometry, this end mill reduces vibration, extends tool life, and maximizes
material removal rates (MRR) in hardened steels like H13, P20, S136, and D2 (up to 55 HRC). Ideal for roughing, semi-finishing, and finishing, it ensures superior stability and surface quality in mold & die
manufacturing.
Features:
✔ 4-Flute Variable Helix Design – Breaks up harmonic vibrations for smoother cuts and reduced chatter
✔ TiAlN Coating – Enhances heat resistance (up to 900°C) and 3X longer tool life vs. uncoated tools
✔ High Rigidity Carbide Substrate – Ultra-fine grain tungsten carbide for wear resistance in abrasive steels
✔ Optimized Core Geometry – Balances strength and chip space for deep cavity machining
✔ Precision Ground Edges – Ensures ±0.005mm tolerance and consistent performance
Advantages:
✅ 30% Higher MRR – Aggressive cutting parameters with stability
✅ Reduced Vibration – Variable helix (35°–40°) minimizes resonance
✅ Superior Surface Finish – Achieves Ra 0.8μm in semi-finishing
✅ Versatile Applications – Effective from pre-hardened to fully hardened steels (30–55 HRC)
✅ Cost Efficiency – Fewer tool changes and longer edge life
