The OSG Flat Bottom Carbide Drill with Through Coolant (6.40 mm) is engineered for precise, flat-bottom holes in steel and alloy workpieces, delivering reliable performance in demanding machining tasks.

• Diameter: 6.40 mm
• Drill Type: Flat-bottom carbide drill
• Through-Coolant: Through-coolant design for efficient chip evacuation and cooling
• Length: 3xD length ratio for greater drilling depth
• Coating: EGIAS coating for wear resistance and high-speed durability
• Material Suitability: Optimized for steel and alloy workpieces

The through-coolant feature keeps chips moving away from the tip while delivering coolant precisely to the cutting edge, reducing heat buildup and prolonging tool life. The EGIAS coating minimizes wear under high-speed drilling, enabling consistent hole quality and longer service intervals. The 3xD reach provides deeper holes without sacrificing rigidity, making it a dependable choice for precision work in demanding steel and alloy applications.
