In the demanding world of mold making and precision engineering, tool reliability is non-negotiable. The SAMHO HRC65 Flat End Mill excels where standard carbide tools fail, offering exceptional wear resistance and surface finish quality on heat-treated steels.

Core Technical Advantages

  1. Specialized for HRC65 Hardened Materials
    Crafted from ultra-fine grain carbide substrates with advanced coating technology, providing the toughness to handle hardened tool steels, die steels, and alloy steels up to HRC65. Reduces tool change frequency and lowers cost-per-part.
  2. Optimized 2-Flute Geometry for High Precision
    • Enhance Stability: Reduces cutting resistance and harmonic vibration during high-speed operations
    • Improve Chip Clearance: Large flute volume ensures rapid chip evacuation, preventing heat buildup and tool breakage
    • Superior Surface Finish: Achieves mirror-like results in semi-finishing and finishing stages
  3. High Red Hardness Nano-Coating
    Maintains cutting edge even at extreme temperatures, ideal for High-Speed Machining (HSM) and dry cutting where traditional coolants are ineffective
  4. Full Range of Micro to Standard Diameters (Φ0.2–6.0 mm)
    From micro-precision for intricate electronics and medical molds (Φ0.2 mm) to robust diameters for general mold work (Φ6.0 mm), covering 15+ specialized models to meet any CNC requirement

Professional Application & Industry Use

  • Mold & Die Industry: Precision machining of injection mold cores and cavities
  • Aerospace & Automotive: Milling of high-strength heat-treated components
  • Medical Device Manufacturing: Intricate milling of surgical-grade alloys

Technical Guidelines for Maximum Efficiency

  • Coolant Strategy: Oil coolant for stainless steels; Air/Mist cooling for high-hardness steels to prevent thermal cracking
  • Tool Measurement: For micro-diameters (Φ0.2–1.0 mm), use non-contact measuring devices to protect the precision tip
  • Parameter Tuning: If machine RPM is limited, scale down spindle speed and feed rate proportionally to maintain chip load
