BEYOND HRC60 Internal Coolant Holes 5D Carbide Drills (3.0-5.9mm) - Advanced Cooling for Production Drilling
Experience superior drilling performance with the BEYOND Internal Coolant Holes 5D series in the 3.0-5.9mm range. Featuring precision internal coolant holes technology and 140° point angle, these HRC60 carbide drills deliver exceptional efficiency in deep hole drilling applications. The optimized coolant holes direct high-pressure coolant precisely to the cutting edges, significantly improving tool life and chip evacuation in demanding production environments.
Key Features & Benefits:
- Precision Internal Coolant Holes: Optimized coolant channel design ensures efficient coolant delivery directly to cutting edges, reducing heat buildup by up to 60% in continuous drilling operations.
- Enhanced 140° Point Angle: Wide point geometry reduces thrust force by 55-65%, ensures excellent centering accuracy, and prevents drill walking in production applications.
- Extended 5xD Flute Length: Superior 5:1 depth-to-diameter ratio enables drilling deep holes up to 29.5mm, ideal for complex components and deep cavity applications.
- HRC60 Ultra-Hard Tungsten Carbide: Maximum wear resistance and thermal stability maintain cutting performance through extended production runs in abrasive materials.
- Optimized Coolant Holes Placement: Strategically positioned coolant holes provide balanced cooling to both cutting edges, ensuring uniform wear and extended tool life.
- Reinforced Core Structure: Enhanced web thickness and specialized flute design provide maximum rigidity while maintaining efficient coolant flow throughout the tool.
