In the mold and die industry, threading after heat treatment requires tools with extreme hardness and stability. The SAMHO HRC65 Three-Tooth Series is designed to mill precise metric threads in toughened materials, ensuring your parts pass gauge detection every time.
Advanced Technical Features
- Purpose-Built for Hardened Materials (HRC46–68)
Crafted from premium ultra-fine grain carbide, these thread mills maintain their cutting edge sharpness even under high-load conditions. Ideal for milling threads in heat-treated mold steels, tool steels, and high-strength alloys where traditional taps fail. - Three-Tooth Geometry for Superior Chip Evacuation
The open, three-flute layout is strategically designed to:- Minimize Heat Accumulation: Essential for deep-thread milling in hardened materials
- Rapid Chip Removal: Prevents tool breakage and chip recutting during continuous CNC cycles
- Increase Rigidity: Provides a stable core that resists deflection during lateral cutting
- Variable Helix Design for Vibration Suppression
Unequal helix angles reduce cutting chatter and harmonic vibrations, resulting in:- Smoother Surface Finishes: Reducing secondary cleaning
- Improved Thread Accuracy: Ensures perfect geometric symmetry for internal and external threads
- 5-Axis CNC Precision Grinding
Manufactured with advanced 5-axis CNC technology for strict dimensional tolerances and perfect tooth symmetry, critical for batch production and high-volume consistency
Versatile Threading Flexibility
- Dual-Direction Milling: Handles both right-hand and left-hand internal/external metric threads
- Broad Material Compatibility: Specialized coatings for Titanium alloys, Aluminum, and hardened steels up to HRC65
- Applications: Automotive parts, industrial equipment, and high-precision mold manufacturing
Professional Usage Recommendations
- Cooling Strategy: Optimized for dry cutting or MQL (Minimum Quantity Lubrication) to maintain thermal stability
- Setup: Use high-precision hydraulic or shrink-fit holders to minimize runout and maximize carbide substrate life
- Gauge Detection: Designed to meet strict industrial standards, ensuring threads consistently pass go/no-go gauge tests
