Deep Groove Carbide Radius End Mill Precision 4 Flute H6 For Hardened Steel

Precision Deep Groove Carbide Radius End Mill For Mold & Die Hardened Steel 4 Flutes

Introduction:

Our Precision Deep Groove Carbide Radius End Mill is engineered for high-performance machining of hardened steels (HRC 45-65), mold/die materials, and tough alloys. Featuring a 4-flute design with radiused corners, this end mill delivers exceptional stability, extended tool life, and superior surface finishes in deep cavity milling and 3D contouring applications.

Crafted from ultra-fine grain solid carbide and optimized for high-speed CNC machining, it is the ideal choice for demanding mold, die, and precision engineering industries.

Features:

✔ 4-Flute Design – Balanced for efficient material removal and fine finishing.
✔ Radiused Cutting Edges – Strengthened corners prevent chipping in hardened steels.
✔ Deep Groove Geometry – Special flute design for improved chip evacuation in deep cavities.
✔ Premium Carbide Substrate – Micro-grain tungsten carbide for maximum wear resistance.
✔ High Helix Angle (35°-40°) – Reduces cutting forces and vibration.
✔ Precision Ground – Tight tolerances (±0.005mm) for consistent performance.
✔ Optional Coatings – TiAlN, AlTiN, or DLC for enhanced durability.

Advantages Over Competitors

✅ Extended Tool Life – 30% longer than standard end mills in hardened steels.
✅ Superior Surface Finish – Achieves Ra < 0.4μm, reducing polishing time.
✅ Reduced Vibration – Stable cutting in deep slots and complex geometries.
✅ Higher Feed Rates – Optimized chip clearance allows aggressive machining.
✅ Versatile Applications – Suitable for roughing and finishing operations.
