In tungsten-copper material processing, cutting tools must meet extremely high standards—they need to deliver precise machining and long-lasting durability. The SAMHO 2-flute long neck end mill with rounded corners (D0.2R0.05–D0.8R0.1 mm) is engineered to meet these demanding requirements. Optimized for CNC machining of tungsten-copper, it helps operators achieve efficient, stable, and consistent cutting performance.
Advanced Technical Features
High-Adhesion Diamond Coating for Extended Tool Life
Our proprietary diamond coating delivers exceptional hardness and chemical inertness:
- Wear Resistance: Maintains a sharp edge during prolonged, continuous machining of tungsten-copper.
- Micro-Chipping Prevention: Keeps the coating firmly bonded to the carbide substrate, even under high-speed friction.
Ball-Nose Geometry for High-Precision Tungsten-Copper Machining
The precision hemispherical tip is ideal for machining complex mold cavities, internal corners, and 3D contours in tungsten-copper:
- Superior Surface Finish: Produces smooth surfaces free from cracks or tool marks.
- Electrode Machining Optimization: Perfect for intricate tungsten-copper electrodes, ensuring dimensional stability and surface consistency.
High-Efficiency 2-Flute “Cold-Cutting” Design
The sharp 2-flute geometry reduces cutting heat and improves chip evacuation:
- Maximized Chip Evacuation: Quickly clears abrasive metal particles from the cutting zone.
- Reduced Cutting Load: Minimizes heat buildup, preventing brittle tungsten-copper from cracking under thermal stress.
Ultra-Fine Grain Carbide Substrate with Precision Grinding
High-strength, ultra-fine carbide combined with specialized grinding ensures repeatable, precise machining:
- Dimensional Accuracy: Tolerances controlled within ±0.01 mm for consistent batch production.
- Fracture Resistance: Enhances tool durability, especially in highly abrasive tungsten-copper applications.
