Engineered for precision flat-bottom holes, the OSG Flat Bottom Carbide Drill with Through Coolant delivers clean, accurate results in steel and alloy workpieces. Featuring a 3xD length and EGIAS coating, it’s built for high-speed drilling and long tool life.

• Diameter: 8.40 mm
• Geometry: Flat bottom design for precise termination and a flat bottom surface
• Through Coolant: Through-coolant delivery provides effective chip evacuation and cooling during operation
• Length: 3xD length ratio for deeper drilling while maintaining rigidity
• Coating: EGIAS coating enhances wear resistance and enables higher-speed performance
• Material: Carbide construction, optimized for steel and alloy applications

This combination reduces heat buildup, extends tool life, and improves hole quality, delivering consistent, accurate flat-bottom holes with minimal burrs. The through-coolant system supports efficient chip removal in deep holes, while the EGIAS coating promotes reliable performance in demanding drilling tasks.
