R10 Four Flute End Mill 0.4μm Carbide Ball End Mill H6 For Steel

R10 4 Flutes Solid Carbide Ball End Mill CNC Cutting Tool

Introduction:

The AMG 4-flute solid carbide ball end mill is a high-performance CNC cutting tool designed for precision 3D contouring, semi-finishing, and finishing in hardened steels, molds, dies, and aerospace alloys. Its ballnose tip and 4-flute design provide exceptional surface finish, tool life, and material removal rates (MRR) in demanding machining applications.

Features:

Solid Carbide Construction

• Premium micro-grain carbide for maximum rigidity & wear resistance in hardened materials (up to HRC 60+).

• Reduced tool deflection for stable machining in deep cavities.

4-Flute Design

• Higher feed rates & improved surface finish compared to 2-flute ball end mills.

• Balanced chip evacuation for efficient machining in steels, stainless steels, and superalloys.

Ballnose Tip (R0.5mm – R10mm+ Options)

• Ideal for 3D profiling, mold/die finishing, and complex curvature machining.

• Smooth transitions & reduced step-over marks for superior surface quality.

Advanced Coating (AlTiN, TiSiN, or Nano-coated)

• Extreme heat & abrasion resistance for prolonged tool life.

• Reduced friction & built-up edge (BUE) in sticky materials like aluminum or titanium.

Optimized for Hard Materials

• Excellent performance in:

  • Hardened tool steels (H13, P20, D2, etc.)

  • Titanium & Inconel (with appropriate coatings)

  • Graphite & composites (specialized versions available)

High-Speed Machining (HSM) & Trochoidal Milling

• Stable cutting performance at high RPMs for reduced cycle times.

Typical Applications:

✔ Precision mold & die finishing
✔ Aerospace component machining (blades, impellers)
✔ Medical device manufacturing (implants, prosthetics)
✔ Automotive & energy industry (turbine parts, injection molds)

Why Choose This 4-Flute Ball End Mill?

✅ Longer tool life than 2-flute designs in finishing operations
✅ Higher productivity due to increased flute count
✅ Superior surface finish with minimal post-processing
