In tungsten-copper machining, tool requirements are extremely demanding, requiring not only high precision but also superior wear resistance and stability. The SAMHO 2-flute long neck flat end mill (D0.2–D2 mm) is specifically designed to meet these standards. It helps CNC operators efficiently and reliably machine tungsten-copper materials, enabling the high-quality forming of intricate and complex structures.
Advanced Technical Features
High-Adhesion Diamond Coating for Ultra-Long Tool Life
Our proprietary diamond coating provides exceptional hardness and chemical inertness:
- Wear Resistance: Keeps the cutting edge sharp even during long, continuous tungsten-copper machining.
- Micro-Chipping Prevention: Ensures the coating stays firmly bonded to the carbide substrate under high cutting loads and high-speed friction.
Long-Neck, Flat-Bottom Design for Precision Tungsten-Copper Machining
The precision long-neck geometry allows easy access to deep cavities, narrow slots, and complex mold features:
- Superior Surface Finish: Delivers smooth tungsten-copper surfaces while minimizing burrs and tool marks.
- Precision Profiling: Enables high-accuracy machining of intricate details, including small holes, grooves, and complex shapes.
High-Efficiency Dual-Flute “Cold-Cutting” Geometry
The sharp, dual-flute design reduces heat and improves chip removal efficiency:
- Maximized Chip Evacuation: Quickly clears dust and debris from high-hardness tungsten-copper.
- Reduced Cutting Load: Lowers heat buildup, preventing brittle tungsten-copper from cracking under thermal stress.
Ultra-Fine Grain Carbide Substrate with Precision Grinding
Crafted from ultra-fine grain carbide and precision-ground for tungsten-copper applications:
- Tight Dimensional Control: Maintains tolerances within ±0.01 mm for consistent batch production.
- Enhanced Fracture Resistance: Withstands highly abrasive tungsten-copper machining, extending tool life.
