Description: Carbide micro drill bit, made of tungsten steel, with high hardness, high wear resistance, high strength, resistance to bending, anti-breakage, etc. Features: 1. Precision machining by high accurate equipment; 2. With good milling and cutting performance, ensuring high efficiency; 3. High hardness, wear resistance, and intensity; anti-bending; 4. To removing chips, with big space and small resistance; Smooth chip removal, less heating value, to reduce pollution; 5. Sharp cutting edge, reduce cutting force, lower breaking rate and improve the quality of hole wall; 6. Symmetrical cutting blade, help to high effective cutting, avoiding drilling offset. |
