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.
