The OSG Flat Bottom Carbide Drill with Through Coolant is a precision tool designed for flat-bottom holes in steel and alloys, delivering reliable accuracy and clean hole bottoms. With a 3xD length and EGIAS coating, it combines depth with robust wear resistance for demanding drilling tasks.

• Diameter: 8.50 mm
• Geometry: Flat bottom drill for precise, true-flat hole bottoms
• Length/Ratio: 3xD drilling depth for deeper holes per pass
• Coolant: Through coolant design for efficient chip evacuation and cooling
• Coating: EGIAS coating enhances wear resistance and high-speed durability
• Material compatibility: Optimized for steel and various alloys

This drill helps machinists achieve accurate, reliable flat-bottom holes with reduced heat and longer tool life. The through-coolant design improves chip evacuation and cooling under high-speed drilling, while the EGIAS coating supports fast cutting and wear resistance in tough applications.
