Internal Cooling Drill Bit
Original Quality with Internal Coolant & Anti-BUE Coating: Made with Sandvik-produced carbide substrate and a specialized wear-resistant coating, this drill features an internal coolant design that delivers cutting fluid directly to the cutting zone for efficient heat removal. The coating is optimized for difficult-to-cut materials like stainless steel, effectively preventing built-up edge (BUE) and extending tool life significantly compared to external-coolant drills.
5D Optimized Flute with Coolant-Assisted Chip Evacuation: The 5× diameter flute geometry is designed for smooth chip evacuation, aided by the internal coolant flow. Even long chips from stainless steel are efficiently flushed out, preventing clogging and tool jamming in medium-depth hole machining, ensuring consistent hole surface finish and dimensional accuracy.
High-Rigidity Solid Carbide Construction for High-Efficiency Batch Machining: The solid carbide structure offers excellent rigidity and vibration resistance, enabling stable high-speed/high-feed drilling with minimal hole deflection. It is compatible with CNC machines with internal coolant systems, ideal for mass production of medium-depth holes in automotive, hydraulic, and mold industries.
