Precision mold-making and aerospace components require tools that can withstand extreme heat while maintaining a perfect hemispherical geometry. The SAMHO HRC65 2-Flute Ball Nose Series delivers exceptional dimensional accuracy and mirror-like finishes on materials up to HRC65.

Core Engineering & Technical Benefits

  • Specifically Engineered for High-Hardness Steel (Up to HRC65)
    Manufactured from an ultra-fine grain carbide substrate, these end mills possess the fracture toughness needed for hardened tool steels and die steels. The high-performance wear-resistant coating ensures long tool life and stable performance during prolonged finishing cycles
  • 2-Flute Geometry for Efficient Chip Evacuation
    Ample chip space is critical when machining deep cavities or narrow 3D contours:
    • Greater Stability: Ideal for semi-finishing and fine finishing
    • Improved Accuracy: Consistent radius tolerance for perfect rest milling and blending
  • Optimized for Complex 3D Contouring
    Precision-ground hemispherical tip:
    • Surface Finishing: Eliminates scalloping marks in complex 3D profiles
    • Intricate Features: From micro-molds (R0.15 mm) to large die cores (R10 mm), ensuring surface integrity across all scales
  • High Red Hardness Coating for Dry Machining
    Thermal-resistant coating maintains edge sharpness at elevated temperatures, supporting high-speed machining (HSM) under dry or MQL conditions, enhancing sustainability and reducing manufacturing costs

Comprehensive Model Selection (36 Models)

Covers a diameter range from Φ0.3 mm (R0.15 mm) to Φ20 mm (R10 mm). Perfect for micro-medical components or large-scale automotive dies, all in stock for immediate use

Usage Guidelines for Peak Performance

  • Overhang Sensitivity: For best results, use the shortest possible overhang. If the overhang exceeds 3×D, decrease spindle speed and feed rate proportionally
  • Coolant Strategy: Use Air/Mist cooling for hardened steel and oil coolant for stainless steels or heat-resistant alloys
  • Setup Safety: Use non-contact tool setters to avoid damaging the radius during setup
