In the machining of high-hardness and heat-treated steels, tool precision and durability are critical. The SAMHO specialized coated 2 flute flat end mill (D0.1-0.8 mm) is engineered to meet these demanding requirements. It delivers exceptional cutting accuracy and superior wear resistance. Designed for high-hardness and heat-treated steels, this end mill enables CNC operators to achieve efficient and stable milling, improving both machining quality and production efficiency.
Advanced Technical Features
High-Adhesion Coating for Ultra-Long Tool Life
SAMHO’s proprietary coating technology provides tools with exceptional hardness and chemical inertness:
- Wear Resistance: Maintains a sharp cutting edge even during prolonged, continuous machining of high-hardness and heat-treated steels.
- Micro-Chipping Prevention: Ensures the coating stays firmly bonded to the carbide substrate under high-speed cutting and high-friction conditions.
Cutting-Edge Geometry Optimized for High-Hardness Steel Machining
The precision 2-flute flat-bottom design enables efficient cutting and stable chip evacuation:
- Efficient “Cold Cutting” Effect: Sharp dual-flute geometry reduces cutting heat and minimizes heat accumulation, preventing cracking in brittle steel.
- Optimized Chip Evacuation: Quickly removes metal particles from the cutting zone, ensuring stable machining and superior surface finish.
Ultra-Fine Grain Carbide Substrate with Precision Grinding
- Dimensional Accuracy: Strict tolerance control within ±0.01 mm ensures consistent performance across batch production.
- Fracture Resistance: Significantly improves tool durability, ideal for machining highly abrasive, heat-treated steels.
Applications
- 2D and 3D milling of high-hardness and heat-treated steels.
- Machining mold cavities, precision components, and small-batch, high-precision parts.
