The OSG Flat Bottom Carbide Drill with Through Coolant is a precision cutting tool designed for flat-bottom drilling in steel and alloy workpieces. With a 3xD depth capability and through-coolant design, it delivers deep, clean holes while maintaining temperature and chip control for reliable performance.

• Diameter: 11.40 mm
• Flat Bottom Geometry: creates true-flat holes ideal for seating and precision assemblies
• Length-to-Diameter Ratio: 3xD for deeper, controlled drilling without sacrificing accuracy
• Through-Coolant: channels provide efficient chip evacuation and active cooling during cutting
• Coating: EGIAS coating enhances wear resistance for high-speed, durable operation
• Material: Carbide construction delivers rigidity and long tool life in tough materials

The combination of through coolant and EGIAS-coated carbide supports higher cutting speeds and extended tool life by reducing heat and wear. Flat-bottom precision enables accurate hole bottoms for reliable seating, while the 3xD depth rating allows deeper holes in demanding drilling tasks. This tool is designed for machinists who demand accuracy, durability, and dependable performance in challenging applications.
