The OSG Flat Bottom Carbide Drill with Through Coolant is built for precision flat-bottom holes in steel and alloys, delivering reliable performance for demanding machining tasks.
With a 3xD length ratio and through-coolant design, it reaches deeper into tough materials while maintaining effective chip evacuation and controlled cooling. The EGIAS coating enhances wear resistance, enabling higher-speed operation and longer tool life in challenging applications.
- Diameter: 18.50 mm
- Drill geometry: Flat bottom for accurate bottom dimensions
- Length ratio: 3xD for deeper hole capability
- Through coolant: Through-coolant design improves chip evacuation and cooling
- Coating: EGIAS coating for enhanced wear resistance
- Material: Solid carbide for rigidity and longevity
- Recommended materials: Steel and alloys
This combination of through coolant, flat-bottom geometry, and carbide durability enables precise, clean flat-bottom holes with consistent tolerances. The EGIAS coating supports higher cutting speeds and extended tool life in demanding drilling tasks, while the 3xD depth capability helps maximize productivity by reducing setup changes and passes.
