In tungsten-copper machining, tool requirements are extremely demanding, requiring both precise accuracy and exceptional durability. The SAMHO 4-flute flat end mill (D1–D12 mm) is engineered to meet these high standards. It is specifically designed for CNC operators to efficiently machine tungsten-copper materials. The four-flute design ensures smooth, consistent cutting while extending tool life, making precision machining more reliable and productive.
Advanced Technical Features
High-Adhesion Diamond Coating for Ultra-Long Tool Life
Our proprietary diamond coating provides exceptional hardness and chemical inertness:
- Wear Resistance: Maintains a sharp cutting edge during prolonged, continuous machining of tungsten-copper alloys.
- Micro-Chipping Prevention: Keeps the coating firmly bonded to the carbide substrate, even under high-speed friction.
4-Flute Flat End Mill Geometry Optimized for Tungsten-Copper Machining
The precision 4-flute design delivers stable cutting forces, ideal for flat surfaces and complex contours:
- High Surface Finish: Produces smooth, burr-free surfaces on tungsten-copper components.
- Precision Cutting: Designed for high-hardness, brittle tungsten-copper materials, ensuring accuracy and consistency.
High-Efficiency Multi-Flute “Cold Cutting” Design
The sharp 4-flute geometry reduces cutting heat and improves chip evacuation:
- Efficient Chip Evacuation: Quickly clears metal powder from the cutting zone, reducing tool wear.
- Reduced Heat Buildup: Prevents cracking or deformation in brittle tungsten-copper materials caused by thermal stress.
Ultra-Fine Grain Carbide Substrate and High-Precision Grinding
Built with a high-strength, ultra-fine grain carbide substrate and high-precision grinding process:
- Strict Dimensional Tolerances: Controlled within ±0.01 mm for consistent batch production.
- Excellent Fracture Resistance: Enhances tool durability, especially for highly abrasive tungsten-copper machining.
