Sandvik Original Quality with High-Performance Coating: Made with Sandvik-produced carbide substrate and a specialized wear-resistant coating, this drill offers excellent hardness, chipping resistance, and anti-built-up-edge performance. It delivers consistent results across carbon steel, alloy steel, and stainless steel, significantly extending tool life compared to standard carbide drills.

 

5D External-Cooling Design for Stable Medium-Depth Hole Machining: The 5× diameter flute geometry is optimized for smooth chip evacuation, even with long chips from stainless steel. Combined with external cooling, it ensures efficient heat removal, preventing clogging and tool jamming while maintaining high hole accuracy and surface finish.

 

High-Rigidity Solid Carbide Construction for Versatile Compatibility: The solid carbide structure provides exceptional rigidity and vibration resistance, enabling stable high-speed/high-feed drilling with minimal hole deflection. The external cooling design is compatible with standard CNC machines, lathes, and drill presses, ideal for mass production in machinery, automotive, and mold industries.
