The OSG Flat Bottom Carbide Drill with Through Coolant is built for precise, flat-bottom hole drilling in steel and alloys. Designed for machinists who demand reliability and finish, it combines a flat-bottom tip with through-coolant and a tough EGIAS coating to support high-speed performance and long tool life.

• Diameter: 8.20 mm
• Geometry: Flat bottom tip for clean, accurate bottom surfaces
• Length: 3xD length-to-diameter ratio for greater drilling depth
• Through-Coolant: Through-spindle coolant for efficient chip evacuation and cooling
• Coating: EGIAS-coated for enhanced wear resistance
• Material: Carbide construction for rigidity and heat resistance
• Applications: Suitable for drilling steel and alloy materials with demanding tolerances

Through coolant improves chip evacuation and cooling during operation, reducing heat buildup and extending tool life. The EGIAS coating boosts wear resistance, enabling higher cutting speeds and longer service intervals without sacrificing accuracy. The 3xD depth capability lets you reach deeper holes in a single pass, improving productivity while maintaining precise, repeatable results in challenging materials.
