SDF-G Series General Purpose Enhanced Internal Cooling 5D (Five-Diameter) Solid Carbide Drill

1. Product Overview: The SDF-G series general purpose enhanced internal cooling 5D solid carbide drill is a high-performance tool designed for efficient machining. Manufactured from high-quality micro-grain tungsten carbide, this drill ensures superior performance on hard materials such as hardened steel (HRC55°). It is suitable for various precision mold and component machining tasks, achieving efficient and high-quality drilling operations across different materials.
2. Internal Cooling System: Equipped with an advanced internal cooling system, the drill delivers coolant directly to the cutting zone via internal channels. This design provides superior cooling efficiency, extending tool life and significantly enhancing machining accuracy and surface quality. The efficient cooling system effectively reduces cutting temperatures, minimizes thermal deformation, and ensures stable machining processes, supporting prolonged continuous operation.
3. Optimized Flute Design: The drill’s flute geometry is meticulously designed to optimize chip evacuation, ensuring smooth chip removal. This design reduces issues like chip clogging and overheating, thereby improving work efficiency and processing reliability. The optimized flute also helps increase drilling speed and quality, further enhancing machining efficiency.
4. ALCRONA High-Wear Resistant Coating: The surface is coated with ALCRONA high-wear resistant coating, which significantly enhances the drill’s resistance to high temperatures and wear. This coating maintains stable cutting temperatures under high-speed machining conditions, reduces friction, and decreases wear rates, thereby dramatically increasing the tool’s service life and machining efficiency. The application of ALCRONA coating ensures excellent performance even after prolonged use, especially for high-intensity and challenging machining tasks.
5. Five-Diameter Length Design: With a length five times its diameter, the drill offers excellent guidance and stability, contributing to precise drilling results. This design effectively reduces deflection and vibration, ensuring straightness and roundness in the drilled holes. The five-diameter design excels in deep-hole drilling, making it ideal for applications requiring high precision and stability, such as aerospace, automotive manufacturing, and heavy machinery industries.
