The OSG Flat Bottom Carbide Drill with Through Coolant (3xD) and EGIAS coating delivers precision flat-bottom drilling for steel and alloy workpieces. Built for machinists who require reliable performance in demanding tasks, it combines deep reach, efficient cooling, and wear resistance for high-speed operation.

• Diameter: 6.30 mm
• Drill Geometry: Flat Bottom carbide drill designed for clean bottom holes
• Length-to-Diameter: 3xD for greater drilling depth
• Coolant: Through-Coolant design enables effective chip evacuation and cooling
• Coating: EGIAS coating enhances wear resistance and high-speed durability
• Recommended Materials: Steel and alloys for demanding drilling tasks

This through-coolant setup improves heat management and chip removal, helping to extend tool life while maintaining accuracy. The EGIAS coating supports higher-speed performance in tough materials, making it suitable for precision work where reliable bottom geometry and consistent results matter. With the 3xD length, you can reach deeper holes in fewer passes, reducing cycle times and improving overall machining efficiency.
